i'm 46 and dealing with it since i was in middle school. more than 30 years. i think it was because i went from a very small elementary school, to a school that had over 5000 students (a combined middle/hs). like, going from a fish bowl thrown into the ocean and i didn't acclimate well at all.
i've been married/divorced and raised my kid who's in college today, who by the way seems pretty normal.
i dont know if the longer you live with it, the more screwed up you become. i guess some get worse and some dont. i deal with it the best i can and i consider myself to be an extreme case. it's definitely not easy and a struggle most days, especially when you realize you dont have friends you can talk to about it without being judged, and that just makes it harder to deal with internally.
