So, I've isolated myself for three years since I was 15 - only going out into town atleast once every 2-3 weeks. I'm 18 now, and recently I have been more "out there" with friends and family. But when I go to public/crowded places I suddenly feel mentally nervous, tense and paranoid..physically I get the sweats and my eyes are constantly moving around my surroundings.
One of my friends insisted I've developed Demophobia over those three years, and another suggested Agoraphobia.
I'd appreciate any answers/comments you have.
