Hey Snakey man,
I'm pretty much the same age as you and I can completely understand the feelings you had for your now ex-girlfriend.

I really do feel for you man, it truely is the most painful feeling in the world, and the feeling of helplessness is truely horrible.

But I guarantee the pain you feel is only temporary. From this you will progress to being a bigger stronger person, life will continue and will improve no end. This is the beginning of something new, to be looked back at fondly.
