My memories keep changing. I started writing things down before I forget everything.

The first time it happened, I didn’t notice it right away.

It was small. The kind of thing you brush off without thinking about it.

Now I can’t stop noticing it.

My doctor told me to start writing things down. He said if something feels wrong, I should document it while I’m still sure of it.

So that’s what I’m doing.

Because something is wrong, and I can feel it getting worse.

Writing this isn’t easy. It doesn’t come all at once. There are stretches where everything feels clear, like nothing is wrong. I can sit down and remember things in order, like I’m doing right now. Then it slips again. Hours pass that I can’t account for. Conversations I know I had but can’t replay. Names that feel familiar but don’t stick. I’ve been coming back to this, adding to it whenever things line up long enough to make sense.

I’ve always lived a pretty structured life. Same routine every day. It makes things easier. The gym is a big part of that. Same place, same days, same time. I don’t talk to anyone there. Headphones in, head down, get through it and leave.

A few months ago, about halfway through my workout, someone tapped me on the shoulder. I turned around and saw a guy about my age already talking.

“You’re bringing it too high,” he said. “Keep it at your chest and squeeze at the bottom.”

Normally I hate unsolicited gym advice, but he didn’t come off like that. He seemed genuine, and he was in great shape, so I tried it.

He was right. It felt better immediately.

“There you go,” he said. “That’s how it’s supposed to feel.”

“Thanks,” I said.

He held out his hand.

“Marcus.”

“Brian.”

“Yeah,” he said.

For a second, I had this strange feeling that he looked familiar. I couldn’t place it, and it went away just as quickly as it came. I told myself I was overthinking it.

I finished my workout, grabbed my bag, and headed out. I had just gotten to my car when I heard my name.

“Brian!”

I turned. Marcus was walking toward me.

“Hey,” he said. “I usually come around this time too. You mind if I jump in with you next time?”

It was a normal question, just phrased a little off. I almost said no.

“Yeah,” I said. “That’s fine.”

“Cool. I’ll see you around.”

The next day, he was there. Same time. Waiting.

We ended up working out together. Then again the next day. And the day after that.

It didn’t feel forced. If anything, it was just easy. We’d lift, talk about random stuff, grab food sometimes after. Nothing serious. Just normal.

There were a few times I noticed he’d show up before I even got there. Not inside either. Outside, near the lot, like he knew exactly when I’d pull in. I asked him about it once.

“Just timing,” he said.

He smiled when he said it.

It didn’t feel like a joke.

After a few weeks I realized I hadn’t really spoken to my best friends Chris and Will. Years of history between the 3 of us. The kind of friendships that don’t need effort. But Marcus lived close, had a flexible schedule, and was always around. Without really noticing it, I started seeing him more than anyone else.

The first time something felt off was when I called Chris.

We hadn’t talked in a couple weeks, which wasn’t normal, so I figured I’d check in.

“Yo, what’s up man?”

“Hey.”

His tone felt off immediately. Short. Distant.

“I’ve been hanging with this guy Marcus he just moved here,” I said. “You should come out this weekend. I’ll introduce you.”

There was a pause.

“I’m busy.”

“Come on,” I said. “We can go to that bar by the train station. The one where you got so drunk you threw up all over the bathroom mirror?”

Silence.

Then he said, “That wasn’t me.”

I laughed. “Yes it was.”

“No. It wasn’t.”

The way he said it made my stomach drop.

“Dude, we literally ran out of there because the bathroom attendant was ready to kill you.”

“I don’t know what you’re talking about.”

Another pause.

“I gotta go.”

He hung up.

I sat there staring at my phone. That wasn’t some small memory. That was something we joked about for years.

“Chris busy?”

I flinched.

Marcus was standing in my kitchen. I didn’t hear him come in.

“Yeah,” I said. “He’s busy.”

Marcus nodded.

“What about Will?”

“What about him?”

“You could invite him too,” Marcus said. “You talk about him all the time.”

“I don’t think I do.”

He smiled.

“You do.”

I didn’t, I had no reason to mention Will.

Will works nights, and we barely talk during the week because of it. When he’s at work, he usually doesn’t have service. Most of our conversations happen when he’s off. He’s one of my closest friends, but he’s not someone I randomly bring up.

Marcus shouldn’t have known who he was.

After Marcus left, I tried texting Will. The message didn’t go through, but that didn’t immediately worry me. That happens all the time when he’s working.

So I searched for him on social media instead.

His profile came up.

And everything about it felt wrong.

It was him. Same name. Same face.

But he wasn’t alone.

He had his arm around a woman. Two kids standing in front of them.

I stared at it, trying to make sense of it.

I clicked into his profile and saw more pictures. Vacations. Family photos. A house.

Captions about his wife. His kids.

None of that made any sense.

Will lived in a studio apartment a few blocks away. He could barely talk to women without getting awkward. He and Chris were my closest friends.

And now Chris didn’t remember something that definitely happened.

And Will had a life that didn’t belong to him.

My head was starting to hurt and I needed to speak to someone reliable, so I called my brother.

Straight to voicemail.

I called again.

Same thing.

My brother always had his phone on him. This was strange.

So I called my mom.

She picked up on the first ring.

“Brian?!”

“Mom? You okay?”

“Oh thank god,” she said. “We’ve been trying to reach you.”

“What do you mean?”

“We’ve been calling you for days. You haven’t answered anything.”

“I haven’t gotten anything.”

She sounded shaken.

“Brian… we were about to call the police.”

Nothing about that made sense.

“Hey,” I said. “Where’s Josh? I’ve been trying to call him.”

There was a pause.

“Mom?”

“…sweetie…”

“Yes?”

“Josh… your brother… he died two years ago. In a car accident…”

Everything after that felt unreal.

I hung up and in a fit of rage spiked the phone to the ground. None of this was right.

I ended up in the bathroom, splashing water on my face, trying to steady myself.

Then I looked up.

And something about my reflection felt wrong.

At first I couldn’t place it. It was me, but not quite. My face looked older. There were marks I didn’t recognize. Small scars I had no memory of getting.

I leaned in closer, trying to make sense of it.

It didn’t change.

Before I even realized what I was doing, I swung.

My fist shattered the mirror.

Glass cracked and fell into the sink and onto the floor. Pain hit a second later, sharp and real. Blood started pouring from my knuckles almost immediately.

I stumbled back and slid down against the wall, staring at the broken pieces.

I didn’t know what else to do.

So I called Marcus.

He picked up immediately.

“I need you here. Something’s happening.”

“I’m already on my way.”

He got there fast. Too fast.

I told him everything. Chris. Will. My mom. My brother.

He listened without interrupting.

When I finished, he looked around my apartment for a moment.

Then he said, “You need something to ground you. Something that will help you remember.”

“What?”

“Write it down,” he said. “Everywhere. Don’t rely on remembering.”

There was something about the way he said it that made me uneasy.

Like he already knew it would work.

We went out and got sticky notes.

Came back and started writing everything down. Names, places, conversations. Everything from that night.

We put them everywhere. Walls. Mirrors. Tables.

Anything I didn’t want to question later.

I must have fallen asleep.

When I woke up, Marcus was gone.

The apartment was quiet.

I looked to my right and there was a sticky note on my nightstand.

I didn’t remember writing it. It read.

“None of this is real.”

My chest tightened.

I got up and saw another note on the mirror.

“Marcus is lying.”

I felt my stomach drop.

I moved slowly out of my room, looking around like I expected to see him standing there.

Another note on the couch.

I picked it up.

Get out. Get help. Now.

I didn’t grab anything.

I just left.

I drove straight to the hospital.

I needed someone to tell me what was happening.

I needed something to make sense.

After hours of tests and waiting, the doctor came back in.

“Brian,” he said. “I’m glad you came.”

“Please,” I said. “Just tell me what’s going on.”

“I know this is a lot to process,” he said carefully, “but you have support. We’re going to help you through this.”

“Through what?”

He hesitated.

“Brian… you’re showing signs of early onset Alzheimer’s.”

Everything around me felt like it collapsed.

Nothing made sense anymore.

The doctor asked if there was someone he could call.

I told him my mom.

He handed me a pen.

I stared at the paper.

I couldn’t remember her number.

He stepped out.

And for a moment, it was quiet.

Then I heard someone move behind me.

“Hey.”

I turned.

Marcus was sitting in the chair.

Calm. Comfortable.

Like he belonged there.

For a second, I just stared at him.

Then it hit me.

He looked odd. Too familiar. He looked like me.

Not the way I look now.

The way I used to.

“How are you here?” I said.

He didn’t answer right away.

He just watched me.

“I heard what the doctor said,” he said quietly. “I’m sorry.”

I shook my head.

“No. No. This started when you showed up.”

He gave a small nod.

“You started writing things down,” he said.

My stomach dropped.

“The notes,” he said. “That helped.”

“Helped who?”

He didn’t answer.

I tried to think.

Chris.

Will.

My brother.

The details felt thinner.

Harder to reach.

“You’re still holding on,” Marcus said.

My chest tightened.

I looked at him.

He looked steady.

Clear.

Like nothing about him was slipping.

Then he said, almost to himself,

“They always do at the end.”

Something in my head shifted.

I tried to picture my own face.

It didn’t feel as clear as his.

“What’s going to happen to me?” I asked.

He looked at me for a long second.

Then he said quietly,

“You will stop feeling the need to remember.”

I don’t remember what happened after that.

I don’t remember leaving the hospital.

I don’t remember getting home.

But I’m here now.

I found this written out.

I don’t remember writing all of it. Some of it, yes. Not all of it.

There are sticky notes all over my apartment. Most of them don’t make sense. Some of the names feel familiar. Some don’t.

There’s one on my mirror.

It looks like my handwriting.

I don’t remember writing it.

It says:

Don’t trust him.

I know who that’s about.

I do.

It’s him.

Marcus.

I can still picture his face.

But it’s harder than it should be.

Like I have to focus just to keep it there.

And the second I start thinking about him…

it feels like something slips.

I don’t think I have much time left where this still makes sense.

If you’re reading this, write things down.

Don’t wait.

Because once it starts…

you don’t notice what you’re losing.

You only notice what’s left.
