I need someone to talk to?

Why are you in such a hurry to define yourself when you don't have a clue what you are? It's not at all unusual for you to have attraction for both sexes at that age. In many cases what you are feeling for your girl/friend is simply a feeling of "closeness" and "deep connection" and not necessarily sexual attraction. Give yourself time. At 13 there are so many other things to be worried about. Give yourself more time and don't go trying to rush into anything you may regret later. Wait until you know yourself, then define who and what you are. I can't think of anything more crippling that to put a label on yourself at such an early age.
