I need serious help.

There's this guy, of course. And, I like him so much. I can't stop thinking about him. He's amazing, utterly amazing. He makes me constantly smile, and feel things I haven't felt before. Seriously, I didn't even think there was such thing as "love" before him. I knew there were feelings and such, but I've never felt this way. I've liked many guys, and I've liked few of them well.. but, not like this. I don't think he's the one I'm suppose to spend the rest of my life with, but I could be wrong.. But, I do know.. That I'm meant to be with him as of right now.. Or, so I think.
But, there's a little problem.. He really, really likes this girl who's dating someone else. And, It's tearing me apart. Not becaue he likes her.. You know. That would tear me apart, but it hurts more knowing he's not happy, because she doesn't like him. It's like eating me alive..

Well, down to the thing I need help with.. Lol.
What do I do?
I know I can't change my feelings for him, and I can't stop constantly thinking about him..
but, how do I..
Well, what exactly do I do?
Am I just stuck like this.. until it's all over, until someone else comes along?
I don't think that will be any time soon, at all..
So, does anyone have advice on how I can stay.. 'up' while this is happening..
;[ I guess that's what I want to know...

This has been told too many times - "there's nothing you can do"

You didn't make one thing clear though. How does he feel about you?

Either way, you shouldn't let this tear you apart. Kinda going against what you said about it being so special, but he is one love out of the many that you would have in your life. I don't know your age..but I'm gonna assume your young and you've still got lots of time to meet other wonderful people =P. If his heart isn't with you...there really isn't any use in dragging it on.

Keep your mind open and bright about the current situation. Goodness is all around you to be found if you look carefully. Try to focus on other aspects of your life. You sound like a person that has a good sense of awareness. You should know there's lots more to life than one single guy...no matter how special he is.
