I think I'm lesbian. I also think I fancy this girl. But then I dont?! Help!

Ok so I may like this girl. Let's just call her Marie? But anyway, when I'm sitting alone and tend to stress and get confused over my sexuality, she pops into my head and how I wish se was here with me right now In my arms. But when Im actually with her I cannot stand her! I think about actually being with her and it repulses me. Not with the girl to girl thing, the whole me to Marie thing! I just don't get it! When I try to get close to her I got my bestfriend thinking I'm ditchin her, my best friend, let's call her Amy. Amy thinks that I'm leaving her out and want to be with Marie instead of her. Amy knows I'm curious about my sexuality but would laugh if I told her I might like Marie (Marie ain't the prettiest of girls) I'm not being full of myself cause I kno I'm not the prettiest of girls but I think I'm better looking than her by miles. Does that make me a bad person. Well anyway, I defo fancy this girl, let's call her Katie and no that she is straight, (Marie is bi) I sometimes think, as bad as it sounds, using Marie and using her to pretend that I'm actually with Katie Im so confused right now. I think I like her but then I think I don't? Help!

If you "think" you might be a lesbian and you "may like this girl," that's saying you aren't sure. Being confused is like trying to see far away in an early morning fog. The best thing to do is to wait until the sun comes out and everything comes into focus. Just chill out until the sun comes out and trust me, it will.
