Um, just to add to that, if it is on your mind, and you want to talk, your local Connexions should have an LGBT (Lesbian, Gay, Bi, Transgender) worker, or there may be a general counselling session in your area. Not sure how old you are, but schools and colleges often have counsellors. Also, if you are 16+ (I think) check out www.horsesmouth.co.uk, an online mentoring service featuring people who have "been there and done that" on just about every topic you can think of! It helps to chat. Have you got a good mate, or someone you know well enough to explore your feelings with?
