I don?t know how I?m ever going to get over this, how can I get over someone when I love them so much. Even though he?s hurt me, more than I?ve ever been hurt before, I can?t even hate him.
Ok, I'm not sure that I used the same quote, letter by letter, but I think that I've say 87% of what you've just say up there, a few years ago.
Anyway, enough with making a fool of myself, getting down to business!
Time heals all wounds(I didn't believe it either, at first).
The best thing is not to think about it(I know easier said than done

)
But think about something that'll distract you from your emotional pain.
See a comedy(not a romantic one, because you'll go like: "why does the hero always get the girl?" and feel bad about your ex), or see a philosophical flick(a documentary, or something to make you pounder and distract you).
Don't go all emotional and self-destructive(you may think that sad music and tons of chocolate help, but on the long run they only prolong your sorrow; I know, because I've been there)
Oh, almost forgot, considering your delicate state(and your emotional nature) it will do you a lot of good if you stop being pessimistic.
Probably you think you're ugly, unattractive and don't have any skills, friends, goals or things to make life worth living. That's not true(if that were true then who could you have had a boyfriend?).
Try thinking: "Hey, maybe my life's shit"(although that's not true)"but at least I've had one sweet moment of pleasure and love in it". "Who knows maybe similar time will come? Maybe even better times will come?"
Anyway if you really feel that you need to get over him, because you didn't "screwed up" anything.
Unfortunately I'm not such a great advice giver, but I'll try to end on a high note:
There will always be someone more "pitiful" than you: some people don't even get to taste love, some people die young because of social problems, some people never had a steady relationship(take me for example), some people have a genetic problems and can't feel love or pain.
Don't worry, because when you're down, there's no place to go but up!(man, do my moralising speeches suck or what?)
