I have fibromyalgia; it developed after an extremely traumatic event when I was a teenager, and ever since then, the chronic pain has gotten worse and worse. It's like having multiple dull cramps, spread across your body (typically joints for me), that never, ever go away, and if you get stressed out over one thing for too long, then tough shit, because then those cramps are going to hurt a million times more. Typically after at least one traumatic or highly stressful event, the pain will permanently get worse as well, with varying intensities.
I've tried telling myself throughout the years that I have a chance to live a fulfilling life, and that this won't be able to take away my dreams, but given just how bad things are for me right now, I don't know how plausible that is. Doing anything that isn't sitting on my ass at a desk all day hurts. Fuck, even that hurts to an extent. I can ignore the pain all I want, but it's getting harder and harder to do that, and I don't know how much longer I can feasibly do so.
This isn't even considering the constant brain fog, which can also get worse depending on how stressed I am. This is the symptom that makes me feel the most hopeless. I've never felt so dumb and useless. Life feels like a constant slog. You forget very basic vocabulary; you forget how to form a single coherent thought in your brain; you sometimes forget how to live like an ordinary person at all. Maybe a thought comes, but then it immediately goes, and you won't remember having it, only that you had a thought that was probably important, but it's gone and you aren't remembering it. And you're just so, so fucking tired. Too tired and unmotivated to do anything at all. Even if you wanted to do something, your body and brain won't cooperate with you, so you'll be stuck in a limbo, wondering why you're like this and if you're truly so worthless that you can't even do something so simple as eating or enjoying your hobbies.
