I don't so much worry about the car blowing up, but I do worry about people judging the car I drive, or the way I dress, or how I write, or any number of other things. Or being mean to me because of those things. Or confronting me about things. I hate confrontation, especially the kind where I can't do anything to solve the other person's problem. Feeling helpless makes my anxiety (and related behaviors like picking at my skin) spike and it takes a long time to come down off that spike. I would gladly hide under a desk to avoid confrontation and feeling helpless, except hiding under a desk makes you a weird crybaby, so I probably wouldn't hide under the desk if anyone else were around to see me do it. Also it's a pretty helpless action, isn't it? I'm trying to find ways to vent my anxieties that make me feel better, like accomplishing small household tasks, but a lot of the time I just give up and hide.
Anyway, anxiety. It sucks. Be kind to people. It helps the anxiety.
