I don't know, this may seem ignorant of me, but just why are you so concerned with those who have "betrayed" you and all of this?
Emotional trauma does happen and yes, it does hurt... But the most important thing to do, I believe, is to remind yourself that if these people make fun of you and hurt you for who you are, then they do not deserve to be put in such a position of authority in your life. Don't let these people make you so upset, they don't deserve your time or aggravation.
Most people reject what they can't accept in themselves -- And since they're rejecting you, perhaps they're just not ready to accept difference in society yet.
