Thanks for choosing health care magic for posting your query.
From the description that you have given, its although difficult to comment on with confidence, but it seems that you may be having depression
at this point of time. Your symptoms of hopelessness, sadness, not interested and reduced pleasure are all suggesting the diagnosis.
You should consult a psychiatrist
who can guide you on these issues. He will conduct an interview and then train you in some behavioral therapies
and also prescribe you certain drugs that can make you feel better.
Hope I have answered your query. I will be more than happy to help you if you need any further clarifications.
