I've had all physical problems ruled out with blood tests now, am not depressed, but wondering if I could possibly be suffering from M.E. Constantly tired all the time, have been like this for over 10 years now. Changed my diet, tried exercising (feel worse after this) and now realise whatever is wrong is a long term thing... How long did it take you to get diagnosed? Did you have to see several GPs before you were taken seriously?
