Nothing Interests me anymore

Hi everyone, I am a 24F. I have recently come out of a situationship, actually I was forced out of it because of his commitment issues. It feels horrible to force myself not to talk with him like we used to , though we are still in speaking terms.. Now I am in a constant dilemma whether to hope that he will commit or to move on. Because of this I lost interest in everything.. even eating twice a day is feeling like a lot of work..!
Any solid advice will be helpful, Thanks..
