hi I can understand your situation of difficulty/ emotional disturbance. the breakup of relationship always has a lot of effect on psychological functioning. leading to disturbance in physical function. normally most of them do feel disinterest, anxiety and stress with situation. at present what all your priorities, goal in your life. work on it. This not the place to discuss and guide you better. Please visit any psychologist in your place, I am sure their guidance will help you to handle the problem in a better way. one thing life is always filled with ups and downs, or bitter and sweet in some situations we need to accept the both, but noting is permanent. time is best healer for many problem. take care and stay positive/have hopes.
