You just have to be yourself.If people don't like you purely for the fact your a lesbian it's their (mental) problem and not yours.
Be proud of who you are and be comfortable in your own skin.
You can't help your feelings and there is nothing wrong at all with being a lesbian and if others tell you differentl sod 'em!

Hope i've helped even a teeny weeny bit.

people who hate gay people are racist, ignore them and be happy with yourself :)

if people don't like u for it, then they don't honestly care for u and it's better to know who they are now than to find out later. just b u and let others decide. don't feel bad if they don't like u for it. they're just close-minded. all that matters is that u like u and u r comfortable with u.
