are you hyper sensitive to criticism? It can manifest online too. Judging from your low self esteem and your self conscience attitude, i think you suffer from a personality disorder (i think alot of people here do). I'm just saying because i suffer from avpd (avoidance personality disorder) and you got the signs.
Well whatever, if you want information on it , google. As for your problem, just bite through the pain. I know lousy advice, since i'm in the same deep shit.
