I've been dealing with this periodic spike in anxiety sometime in the afternoon for the last few years. It's not every day per se, but it does seem like it's getting more frequent, and sometimes intense. And today it struck earlier and seems to be lasting longer than usual. And it's downright paralyzing when it hits, which I hatehateHATE. I can't do much of anything productive because I just plain can't focus.
I never used to really understand anxiety disorders and such when I was younger. I've always battled depression, but it's only been 5 or so years where I've started regularly having these issues, and I definitely get it now. It's like this... [i]thing[/i] hanging over your head. Like something horrible has happened or is about to happen but you don't know what it is and can't do anything about it. and you're just sitting there on edge, unable to focus on things or stop spiraling down into everything that's currently not good around you or in the world in general.
Sometimes talking or venting about it helps, but sometimes it doesn't. And the fact that I'm not being productive like I'd planned just exacerbates the issue. There's no doubt that there are factors that can prompt it or worsen it, but it never seems to be about any one particular thing, usually. Which leads me to think there's definitely a physiological factor to it. I really need to press my doctor about that next time I see her. I do know for one thing I need to lay off the caffeine, as I'm sure that's not helping, heh. But other than that, I think it's yet another malfunction to add to the list of problems my stupid broken brain has. >.<
Depression, ADHD, and anxiety make for a hell of a triple-whammy...
