If I'm around people I know well (family/close friends) then it's fine and I seem completely normal but around strangers, potential friends, relatives I haven't spoken to in awhile, simple phone calls, job interviews, and especially in large crowds I feel like I can barely talk because my heart is beating so fast. I've been like this my whole life and part of me not wanting to go to college is literally because I'm afraid of the presentations. I know most people experience nervousness in some of these situations but they seem to be much milder than mine. I don't like telling people this either because it's embarrasing and so I try to hide it as good as I can. Is there something wrong with me or am I over-reacting?
