Feeling depressed over break-up. Help me.

Im at the point of my life now where I dont feel like living anymore. I feel like Im a lost cause after my girlfriend decided to call it off. Its been months since things ended between us but Im still not over her. Not by a long shot. Each day I just feel worse. I dont think I will be able to recover from the grief. I just feel so depressed and lost.

I still remember meeting her for the first time in that foreign dating event. She got my attention the moment we started talking. Since then, Ive imagined a future with her. I thought that that was it. I already found the one. Turns out I was wrong. How do I move on? How do I forget someone whom I was already planning to share my life with? How??
