I'm a girl and I'm in-love with a girl.

Okay so here it goes. I'm a freshman in high school and I like this girl who's a senior in high school. We both attend the same high school by the way. I don't know how to find out if she likes me or not. I'm like really awkward and shy so yeah lol I feel awkward talking to her cause I'm afraid if I talk I'll sound dumb. We change next to each-other in the locker room for PE, witch is even more awkward. I've caught her looking at me like a million times and I don't know why. I really want to tell her but I don't know how. Plus the school years almost over and she's going to college. :/ I always think about her. It's crazy. Please help?

Just tell her how that ur bi then c how she moves after maybe she will ask u out and from there she may make a move or u do

You won't sound dumb don't worry. You have to tell her you're in love with her and ask her if she's into boys or girls. Its her choice from there.
