I know how u man. When i broke up with my last girlfriend i was a wreck. It was like she was the only thing that gave my life meaning and without her i was nothing. But you cant live ur life in the past, its not good for you. I know that it hurts that she is gone, believe me ive felt that pain before, but u cant let it control you. If you truly think that things between you and her can be fixed then go for it, but if she has moved on and has no interest in going back then you have to let her go. What i did when i had to get over my ex was i got rid of everything that reminded me of her, i took her number out of my phone, i got rid of her pictures, i took her of my IM. That was the only way that i could stop thinking about her. And trust me, drinking wont solve anything, it just numbs the pain, it doest get rid of it. Put down the bottle and find something to do that makes you happy. Play a sport, or take up a new hobby, or just go on a vacation for a bit, just get away from all the problem that you have, you will be suprised by how much a little vacation can help you forget your problems. I wish you luck
