My girlfriend of 2 months broke up with me in December. That may not seem like a long time, but it was a whirlwind romance, and I was very much in love. She said she was too, but I doubt that now. Either way, I felt very strongly about her. 

She broke up with me totally out of the blue and I was distraught. I had a lot going for me at work though, so I completely threw myself into that and achieved a lot of personal goals. Additionally I'd been neglecting my friends while we were together, so I hung out with them a lot and was honestly touched by the way they came through for me. I didn't see her except in passing for the entire time, and things were civil if not friendly. I tried not to think about it, and I was content with life, if not happy.

I saw her at a bar on Friday, and man, she looked beautiful, suddenly everything came flooding back. I'd had a lot of wine, so I told her she was a cold hearted bitch. (douchey, yes, but I was drunk and hurt.) She took offence (obviously) and we ended up having a long conversation. One thing led to another and I ended up in floods of tears in her arms. Eventually my friends came over, told her to fuck off, and took me home. For the first time in my life I cried myself to sleep. 

I bumped into her on the streets today. Her friends were making jokes about me which I could just about hear, while she was trying to shut them up. I had to try very hard not to lose it and start crying again.

Now I feel utterly, utterly broken. This is the worst pain I have ever experienced. I think I was suppressing my feelings for a long time, and now they've come back in force. All I want to do is lie in bed all day but I'm scared of being left alone with my thoughts. Has anyone experienced a similar situation? I don't know what to do. Help?
