I'm really obsessively in love with one of my friends at uni. We are good friends, but she knows how I feel and is not interested. But even though I know I have no chance, my life still seems to revolve around her. I think about her all the time, judge myself by whether I am able to make her laugh or not, get depressed if I don't see her, even choose my activities with the motivation of having something interesting to talk to her about. I just need to get over her but I don't know how, cos I think otherwise it might ruin our friendship.
