Evaluation: Frankly, it would be inappropriate for doctors to diagnose you based on the information you provided and without an actual assessment. It sounds like you are feeling miserable. I encourage you to seek evaluation from your primary care provider to look for medical causes for these symptoms. If that evaluation is normal, then a comprehensive psychiatric assessment would be in order.

Need to examine: It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor and discuss if you may be depressed. Counter-intuitive as it may seem, exercise may help. Start with low intensity exercise such as walking and gradually increase the intensity as tolerated. Wish you good health!
