<human>: We have been together since March 2012. We did have a breakup back in May '13 but decided to try and work it out. I thought everything was going well. We were having a lot of fun together and I thought he was happy. He told me that this christmas was the best christmas he has ever had. He talked about marriage and he was so excited about it. He sat me down last night before we started to watch a movie and told me he loves me a lot but that he hasn't been happy for the past 6 months. He said the chemistry has gone and he ended it. 

When we broke up last time it was really bad. I started to see a therapist and was put on anti-depressants. I could not handle the no-contact. It drove me to the brink of insanity. I am away for college right now so I have no family around. I have friends but none that I consider real friends, just acquaintances. 

I really do not want to be in a relationship with someone who says the chemistry is gone but I don't know how to get through this. Everyone always tells me just keep yourself busy, work out, block contact, but it doesn't work for me. I stop eating. I stop sleeping. My hair starts to fall out. I go out with friends but I my mind is always on the situation no matter how hard I try to forget. I am so determined to not be in this situation and I want to be happy. I know the relationship is unhealthy for me but I don't know how to cope with him not being there. 

What should I do? I'm in a state of shock right now because I was not expecting it. He says he is going to do whatever he can to help me through it. I appreciate it but I just don't know how it is going to work. I have an appointment with my counsellor on Friday.

Can you condense the text into three sentences or less?
