I was diagnosed last year, but am doing much better. I saw a naturopathic doctor as well as an acupuncturist. I took more supplements than I ever have in my life, but it did really help. I got past the worst of it. If you can, get a consult with a holistic doctor/nutritionist, who I believe is more likely to provide some help.
For me it involved LOTS of extra protein, especially in the a.m., vitamin C in very high doses, kelp/iodine to support my thyroid, iron, high levels of B complex, magnesium/calcium at night and some adjustments to my schedule to help my sleep, melatonin at night to get me back into some sleep at least, sleeping late as much as possible (at least when DH was home). No caffeine, lowest sugar possible, whole foods, avoid preservatives. Honestly, it is probably what everyone should eat but most of us don't!
