<human>: Provide a brief overview of the text.

Things have been wild in my life recently. The people I'll be discussing are 17. I'll start off with a few things about my friend. He has been struggling to get a girlfriend for so long and he will literally do anything to get one. He says he's been treated with "Schizophrenia" but at such a young age? It's hard to believe. Anyway, he says he hurts himseff (cutting) and all sorts of other things. There's this one girl that he's known for a while, but so have I. He is absolutely obsessed with her. He is so overprotective for her and he places his whole life on the line for her. He says his life has no meaning without her, even though they aren't even dating. In fact, she told me herself that she does not, and will not, like him more than a friend. Instead, she told me that she likes me and it just so happens that I like her too. Once he found out that me and her were starting something, he completely exploded. He kept telling my how much he cared for her and how much she means to him until it got to the point where he pretty much said "Fuck you" and left me. We've been dating for about 2 week and it seems that he just keeps getting worse and worse. He won't even talk with me anymore. I've known him ever since I was a child, as well as the girl. All three of us walk within a 2 minute walking distance. I'm not sure if I should leave her, even though we really like each other, or if I should attempt to get my friend back. He's already said some mean stuff about me so I don't even know if there is a way back. Any help would be appreciated, I don't know what to do.. Thanks..
<bot>: Long time friend hates me because I took the love of his life, even though she stated she won't like him, and she likes me. Now everyone is upset and I don't know what to do.
