<human>: I'm 17, male. About 3 weeks ago my girlfriend of only a month left me for no apparent reason, for one of my best friends whom she is now going out with. Everything was going so perfect, we were both really happy. I did everything for her, and out of nowhere she "just wants to be friends". I got angry and we got into a fight, so we aren't friends anymore. She was the first girl I ever loved, and I thought we would be together for a really long time.

I just want to get over her now. There's no hope in another relationship with her, after all this drama. I haven't talked to her since, but it doesn't matter what I do, I'm constantly thinking of her. I'm never happy, and the stuff I used to love (like games, movies, going to parties, etc) doesn't make me feel any better. I have to see her every day at school, and she's part of the group of people I always hang out with, making it really hard. I wish I could avoid her, but it's not that easy, and I'm too pissed to "just be friends". All I want is her, and I can't get what I want, so I'm not happy. I walk around every day like a zombie. I feel like I have nothing, even though that isn't true. What do?

Give me a shortened version of the text
