Well, my girlfriend of eleven months left me for someone else kinda recently. She was a year older than me (I'm 17 now, 16 at the start of the relationship) and so she's now at University while I'm still stuck at school - 450 miles away from her.

We were always together. I dropped everything for her and I'd have done anything for her. Without realising it I alienated myself from all my friends over the time we were together. They've been fantastic to me, supporting me and telling me she's a bitch etc. I don't know what I've done to deserve them to be perfectly honest.

My problem is that it will have been a month this time next week since we broke up. I can't take my mind off her at all. I wake up thinking about her in the morning and I go to sleep thinking about her too. That's if I sleep. And should I get a few hours, I dream about her. I woke up at 5am shaking after a dream I had about her. I've completely gone off food. I've had three meals since Monday and one of those is only because my parents practically forced it down my throat.

I know I shouldn't, but I can't stop thinking about her. And whenever she signs into an IM, I end up talking to her. She always talks about how she cares, and wishes that I didn't feel so bad. Which has me alternating between rages (e.g. "Don't say you care. If you cared you wouldn't have done it") or complete depressions (where I cry into my hands and don't talk) because she seems so genuine. I'm kinda scared because after one of the more recent ones, I walked up to some cliffs near my house with a bottle of vodka at 1am. I don't know what the fuck I was planning on doing when I got there but I turned back after a while.

I've tried deleting her number. Her IM. Got rid of her facebook. Deleted pictures I had of her. Sent away everything that reminded me of her in a box. I got it all back apart from the box.

Help me, what should I do?
