well, yesterday a friend of mine admitted she likes me. i told her that i had to really think about it before getting back to her about how i feel towards her, and she understood, which was really nice of her. meanwhile, i'm freaking the **** out. i have never really had a successful relationship and also never had a same sex relationship before (i'm a bisexual female) and i'm going crazy with anxiety. i don't know how i feel towards her, but i'm lost on what to say to her if i turn her down. i've messed up relationships and friendships so many times that i'm terrified. help?
