I think it must be a very serious health problem. Can it be cured ? My health is also no good lately . I was sick and my family is looking after me . I stayed at home most of the time . I think you may have the same problem as me . But you are unable to rest as you need to work and study. Or maybe your problems can be much more serious than I thought. However, try to think positive first. What ever that happened just take it with courage . Do not think over the past of what has happened. It may not help at all. Only your own will power and happiness can help you to pull through....
