So, I'm really into this girl, she's in the same class as me and we're pretty good friends. The bad part is that only I start talking to her. I mean, if I don't initiate a dialogue she can ignore me for days (she's kinda shy, but that's not the reason). I haven't told her about my feelings, but I don't think it would do much. Also, I'm super depressed, so a refuse wouldn't help me too much. I don't know what to do, but I need to do something fast, because I'm slowly losing my mind. What should I do? Should I cut her out of my life? Should I tell her what I feel about her? Help me, please.

Edit : I don't know if it helps but I'll write this down as well. Basically, my entire class knows that I like her. Hell, I think even she knows it. So, when someone said something about the two of us she said she has "nothing to do with me", but I don't know if it was a joke or she really meant it.
