I'm totally with Alohajen...
I avoid places with bright/flickering light, music, movement, smells. It's just too much. No alcohol, but it feels like a huge hangover.
Whenever I'm preparing to go to a social event (rarely), the dressing up already consumes all of my energy. After 5-10 minutes I start getting very aggitated, just out of the shower, fresh clothes, nice hairdo, then I start sweating like a pig, need to undress again to cool down - put my hairdryer on (cold, not warm) to cool down and make my head stop sweating.
Last year, I got myself ready at a friend's house, together with some other friends; They looked at me as if they were seeing an alien. They said they never saw something like that. I think that the people that were present then saw with their own eyes in what bad shape I'm in.
If the event is not that far from home, we take both cars, then I can get back home when it's starting to get too much.
