hi I'm a 41 yr old female I am constantly fatigued no energy. I cant concentrate or focus, its exhausting to even have a conversation, I recently started a new job with long hours , and lately I have been becoming so fatigued over heated and sick that I can barley drive home, I latterly feel like I should be in hospital I get so sick, once I rest I feel a little better, but I never really feel good I have been to many doctors who just blame it on my depression. but I'm really sick what is wrong with me? and what can I do? thank youy
