make a move?

I'm so terrible at telling when I have a crush on someone vs. if I just want to be friends w them. There's this girl I think I like (but also idk?) and I think she has the same idk kind of feelings about me. Is it ok to ask her out or is that leading her on? I think I want to, but there's a chance I might just want to be friends after the first date. A big part of this is my anxiety disorder that makes me super anxious in situations others might not be as anxious in.
