It would really help if you had someone to talk to. Is there a way you can see a therapist - someone who would accept you? A trusted counselor?
This is really hard to do all by yourself. It's hard (but sometimes necessary) to keep a whole piece of yourself from your parents or your friends.
Is it that you don't think they would accept you?
Is there a PFLAG near you? Or any other LGBT organization? Sometimes they'll have phone numbers you can call and can suggest something.
Of course there are lots of us here at Susan's, but it's not the same as having someone in your life who is on your side.
