CFS Question

Does anyone have any good tips on how to help fatigue.  I've tried ritalin for my ADD, antidepressants, sleep studies, excersize, accupuncture, more sleep, diets, and I've had all my blood work checked...NOTHING WORKS and my blood was fine! I do have hypothyroidism but havent had problems since I was diagnosed with it.  I take synthroid on a daily basis and my levels are normal and have been for years.  I've had my heart checked just to make sure that wasnt a problem, and it was normal...no problems. All the doctors I've seen seem to be at a loss with me! All of them just say O you must be depressed... im on the antidepressants right now and NO change!! I feel like i'm going crazy!! I'm always tired!! No energy!!! Noone knows what to do with me....and i'm just hoping someone out there can give me tips? simular stories? ANYTHING! I'm getting desparate!! PLEASE SOMEONE HELP ME!
