I Didn’t Forget, My Brain Just Left

I walked into the kitchen the other day and just stood there. Not thinking, not remembering, just there. I knew I came in for a reason. I could feel it, but it was gone. Not the kind of gone where it’ll come back in a second. I mean completely gone, like my brain just closed a tab without asking me.

So I did what I always do in that moment. I opened the fridge, stared into it for a few seconds, grabbed a bottle of water, and told myself that must have been the plan all along, it wasn’t.

If you live with fibromyalgia, you already know. That’s fibro fog. Some days it’s light, annoying but manageable. Other days it feels like my brain just doesn’t show up. Words get stuck somewhere between my head and my mouth. I lose my train of thought mid sentence and just sit there, wondering what I was even saying. I’ll start doing something and forget what I’m doing while I’m still doing it.

It’s frustrating in a way that’s hard to explain unless you’ve felt it. It’s not just forgetfulness. It’s something doctors actually recognize as a cognitive issue linked to fibromyalgia. They call it “fibro fog,” but what it really comes down to is problems with memory, focus, and processing speed. Basically, the parts of your brain that help you think clearly are slowed down or overloaded.

A lot of it is tied to what your body is already dealing with. Chronic pain pulls on your attention constantly. Poor sleep means your brain never fully resets. Fatigue drains the energy your brain needs to function. Some research even points to how the nervous system processes signals differently in people with fibromyalgia, which can affect concentration and mental clarity. So it’s not random, and it’s definitely not in your head in the way people sometimes mean it.

It’s one thing to forget your keys. It’s another to hesitate before you speak because you’re not sure the right word will come out. You laugh it off because what else are you supposed to do, but inside, it doesn’t feel funny. I remember sitting down to write a simple email. Nothing serious, just a quick response. My mind went completely blank. Not a “give me a minute” blank, just empty. I stared at the screen longer than I want to admit, trying to pull the thought back like it was hiding somewhere just out of reach. It never came back.

I felt frustrated, but also a little shaken. How do you explain that to someone? How do you explain that your brain just stopped cooperating out of nowhere? That was one of the moments I had to remind myself this isn’t laziness. This isn’t me not trying hard enough, this is fibromyalgia.

Once I really accepted that, I stopped fighting myself so much. Now I work around it. I write almost everything down. If I don’t, there’s a good chance it’s gone. I set reminders for things I used to just remember without thinking. At this point, if it’s not in my phone, it doesn’t exist, and yes, I’ve set reminders and then forgotten why I set them.

Some days I handle it well, some days I’m patient. I take my time, I laugh when I can, but other days I don’t. Other days it gets to me. I get irritated, and tired of feeling like I’m not as sharp as I used to be. That’s something people don’t talk about enough. It’s not just the forgetting. It’s what it does to how you see yourself.

When your brain feels unreliable, even for a moment, it shakes your confidence in a way that’s hard to put into words. You start second guessing things you never used to think twice about. Simple conversations feel harder. Tasks take longer, and even though you know what’s happening, it still gets to you.

I’m learning slowly that I’m not defined by those moments. I’m still me, just moving a little differently now. One thing that helps sometimes is saying things out loud. “Keys are on the table.” “Phone is in my bag.” “I’m going to the kitchen for water.” It sounds small, but it helps keep me grounded and present.

I’ve also learned that pushing through it usually makes it worse. When my brain is already struggling, forcing it just drains me faster. There’s actually a reason for that too. Cognitive fatigue is real, and once you hit that limit, your brain doesn’t just push through like it used to. It needs a break. Sometimes the best thing I can do is pause for a minute and come back to it.

The world doesn’t slow down for this. Life keeps moving. There are still things that need to get done. I had to learn how to meet myself where I am instead of expecting myself to function the way I used to.

If you’re dealing with this too, you’re not imagining it. You’re not losing it, and you’re definitely not alone. Some days your mind feels clear. Some days it doesn’t. Some days you remember everything. Some days you walk into a room and forget why you’re there, more than once.

It is what it is, fibro fog is frustrating, and exhausting. Some days it really gets under your skin, but it’s not everything. It’s just something we deal with.

On the days when your brain isn’t cooperating, when the words won’t come and the thoughts won’t stick, you’re still you. Even on the foggy days. Especially on the foggy days.
