What should I do? Please Help me! I'm confused?

I don't know your age, but if you are under 20 its sometimes normal to get curious about somebody the same sex.Mainly it is no body's Business who you like.And You can make that clear and simple with all the persistent friends of yours.And my advice don't get too hooked up with that girl.These feeling you have might pass away.I was in your situation when i was in high school, and never said a word about it, never took any action.It was a wise idea because eventually it really passed away.But for the fun of it, if you eventually find out she has similar feelings about girls, you could try to approach her.
