Ughhhh I feel awful

So

My boyfriend broke up with me today and I don't really know how to deal with it. We have the same friend group so I can't really avoid him. I still have feelings for him and he didn't tell me why he broke up with me. I just feel like crap. Gah I hate emotions. I haven't been able to eat at all and I feel extremely depressed. Is there anyway to feel better.
