Hi thanks for query. One statement may be not be enough to say what problem you might be facing, but I can understand that you are emotionally disturbed due personal or professional issues. Lack of coping ability have resulted in disinterest, lack of confidence and others. Please visit psychologist in your place to get better guidance and assessment.

You can try to focus on any thing that interest you for short period at least. Don't put yourself in one corner, try to get along with your loved ones.
