My story is some "500 days of summer" stuff, if you've seen the movie. I fell in love with a girl I met in college. I knew from the very beginning it was unrequited feeling but I just completely lost my mind for her. After a year of so called "friend-zone" something changed, we got closer and eventually we were together for a few weeks, although I could feel it wasn't serious for her (despite we had sex, kissed in public etc., she never realy called us a couple). I never really told her how I feel about her, I guess I was afraid of rejection, and I was kind of happy, I didn't want things to change. However they did, she just started acting as we were just friends again and I couldn't do anything. Now, I'm back when I was a year ago and I feel worse than ever (it started affecting my grades, I can't sleep properly anymore, I can't even enjoy things I used to love like movies). I feel like she was playing with my feelings and I hate her for that (yet I'm still in love with her, is that even possible?). In other surcumstances I would try to move on, broke contact with her, but I see her everyday, we have the same friends, and I can't do it just like that without being awkward about it among my friends (and seeing her everyday isn't exactly helping me in forgetting her). At the same time I know she's not right for me, that she will never feel the same about me how I feel about her. I still have some hope, I'm jealous about her and I'm angry with myself for it. I just want to wipe her out from my mind, and stop thinking about her constantly, but it feels impossible. I'm really exhausted and I have no idea what to do.
