I often feel like this. Luckily I've got enough self-control to be able to prevent this, but supposing I become worse later on in life, and I actually do explode in public? That is my worst nightmare (amoungst other things!), and I just hope I don't get to the point where that happens. I already have a fragile state of mind and poor self-esteem and a lot of anger in me, so I'm surprised that I've lasted this long. Some say that there must be a strength in me somewhere to be able to keep cool with all that going on in my mind!
But anyway, yes, I have felt like I was about to explode, especially in supermarkets. I've seemed to developed this obsessive hatred of standing in people's way, because knowing I'm always getting in everybody's way make me feel so awkward all the time, and what makes me mad is I get in the way even in the most unlikely places. And once I stood in somebody's way and some twat came near me and said, ''excuse me'' and I got so mad that I stuck my fingers up at her when her back was turned (nobody really saw). I just couldn't help myself. My brain suddenly shut down and so I didn't know how else to calmly relieve my anger, so sticking my fingers up made me feel better. Then another time I was trying to look at some clothes in a clothes shop, and a woman came and looked at the same clothes on the small rail, and was standing almost right on top of me, and I felt like screaming.
I mostly feel like exploding when I'm around other women. Men aren't so irritating because they don't stand in your way so much and they don't make you feel so awkward when you're in their way, and they wait 'til you're finished when you're trying to look for something in shops.
