Sounds like you recognize some things that are helpful for you to do. Light, reasonable exercise is usually a good thing for fibromyalgia sufferers - I think some gentle yoga is recommended. As far as the eating - eating healthy doesn't have to be difficult. Do you have some grocery stores that offer delivery in your area? If you have things at home like fruit, yogurt, skim milk, high fiber cereal, Luna Bars, organic soups, bagged salads, rotisserie chicken and so on then eating healthy becomes MUCH easier.
I am doing ok as far as the Graves goes. I am pretty much in denial of the whole thing. My thyroid immunoglobulin is up but the thyroid hormones themselves are ok and I don't feel bad. I have a high threshold for pain and am generally active, I am tired but I have a 5 month old so............ well, duh, I'm tired. So, I researched the illness and found out that there can be remissions and periods with issues, some people do fine with no meds, others need them, treatment is as bad as the disease itself as it can cause a yo-yo effect on the hormones so I'm not anxious to treat it. Basically, anything I can do to work on my stress, exercise and eat healthy is a good idea. I do pretty well as far as eating is concerned - overall, I eat a whole foods, well rounded diet. It isn't easy because my H doesn't care for veggies at all but I fix them for me and the kids.
I just want to encourage you to do some good stuff for you. In a way this is what OM offered - creating a space where you could be yourself, an individual. You can find that same thing other ways. Have you read any of Mama Gena's books? They are all about pursuit of personal pleasure and a must do for any woman.
