I am constantly lathargic with aching joints and pain.I have had all the blood test and all came back normal.I am not depressed I dont need anti depresants. I dont work so im not over worked.I have a good married life.I just feel so ill and weak all the time.Iv been like this for just over a year.I am a vegerterian but I do eat fish two-three times a week.
