I just need someone to see this.

I posted an ask reddit question earlier. I just need someone to see this story and give me some advice.

Here's mine: So about 4 months ago my life started a slow decline. I have legitimately 1 friend. This is an important detail to remember later. So as my life goes downhill I meet this girl who is my age (15) but she's a Freshman and I'm a Sophomore. These are also important details. So as my life starts to fall apart, I became somewhat suicidal, or rather, very suicidal. But this girl man, she kept me going. Just thinking about her. Then I end up with her cellphone number through a friend of hers. One night I was particularly suicidal and my first thought is to try to talk to her to get better. After a little bit, we've reached the point where we can text back and forth comfortably knowing who the other person is. I become non-suicidal. Yay me. Then time goes by, we still talk at least once a day. We see each other in person occasionally as well. We become decent friends if I say so myself. Flash forward to May. I finally have the courage to ask her out. I've never had a girlfriend being 0-5 lifetime in asking girls out. I figure over text is a cheap way to do it but I don't see her enough to do it in person. She rejects me. But here's the best part. I find out later it's on the premise she thinks I'm an 18 year old senior. Yeah. Fuck me, right? So then whatever. This one stings a little worse than previous rejections but hey I'm over it. Then fast forward to last week. It's the last day of school. Remember that one friend I have? Before my final exam of the year I was talking to him and learn that he has a girlfriend. And it's none other than the girl that I attribute to saving my life. I go to his 16th birthday party a week later at which I learn they've been dating since a week after I was rejected. And even worse, I see them together and realize not only is she the perfect woman, I swear by it, but they are the perfect couple. I mean, I'm lucky to know these people but the circumstances could be less saddening. TL;DR I'm in love with my best, and only, friends girlfriend who is not only the best girl alive, but has saved my life at least twice. Now I'm sitting on my couch crying listening to her favorite song on replay over and over. Fuck the Universe, bro.
