I'm 15, how do I get over this guy. I'm getting depressed.?

I feel like I'm inlove with him. I've felt this way for over 2 years. I don't know what to do. He's weird, and I love him just the way he is. He has amazing blue eyes, he is so passionate with his music. Most people would just call him a freak but I see something in him I just can't explain. I just adore him really... he doesn't like me back and we'll never be together. I know this, but I just can't help but wanting to be with him so bad. I'm pathetic for feeling this way but I can't help it. I cry over him all the time. I start fading out of reality, forgetting about him. And we I come back here I am in the same starting place crying my eyes out. It's not like I don't have a life, I'm not ugly, I have friends, I could have another boyfriend if I wanted I guess but I just can't get over him.I can't talk to my friends about this and I just need help on how to get over him. Thank you, sorry for spilling my guts. But 2 years is a long damn time.
