I identify with almost all of it. I know I'm hypomanic when I can't sit still; I'm on my laptop and I can't keep my legs still. I feel agitated and fidgety. I often feel like hiding in my room because I know I am in what I call "troll mode" where I feel like I want to bite people's heads off just because they exist.

Also, I usually lose my filter - you know that thing you have that stops you from saying every thought that pops into your head? That pretty much just disappears, so I will say things I normally wouldn't because for some reason I can't seem to stop it from coming out. I also feel that pressure to keep talking, even though I am actually driving myself insane with it. I think I need to shut up, but I can't.

My mind also does the jumping from one thought to another thing, or it just feels like everything is spinning into nonsense and I can't concentrate on anything. My hypomania episodes are hardly ever pleasant experiences. I don't become productive, I feel on edge and become unpleasant. Fortunately they mostly just last for a week or so. Or maybe not fortunately, as I usually then plummet back into depression, but at least I feel more sociable when I'm depressed. It's easier to hide, even if it still sucks, you know?

Anyway, you are most certainly not alone.
