aww you need to get past it and realise that people who are close to you won't judge you and think you are revolting,
i used to get really bad excema(however it is spelt) on my arms and i wasn't afraid to hide it people asked what it was and i told them, now i have scabs and stuff they look like syringe scabs (ive never pushed) which will not go away but to be honest it doesn;t really bother me anymore!!
you should go out and try to have a good time and then you will realise people who do look at you strangely or in a way that offends you (they are extremly shallow and you shouldn;t even justify them with an answer or let them see you upset) they aren;t worth it, its you and the people who love you!!
you should speck to someone about how you feel!!
i hope this doesn;t offend and i really hope everything works out for you becuase to me it really sounds like you deserve it!! x
