Respected doctors, I am a male of 29 years of age, I am suffering from generalized anxiety disorder feeling like I am in a like state, light headed, foggy vision, stiff head, depersonalization, tough to carry on life since 1 year. One of psychiatrist has suggested me that your body stamina is too weak so eat healthy and sleep good. As soon as your body stamina rises you will be alright is he right. Please suggest.
