I have been taking Levothryxin for about 20 years. Am female, 72 years old, had breast cancer , mast., radiation and chemo., 4 years ago and am currently scan free! Other than that am relatively disease free. I was divorced after 39 years, 14 years ago, so have had some major stress issues. About 8 years ago I started feeling very anxious, depressed, no energy, assorted knee owies and pain spots that would continue for a few weeks, and no sleep. Am on Effexor daily, Xanax as needed for the panic, and Ambien for sleep, that doesn't seem to help any more. I think I should feel better than I do, as it is affecting my life and schedule. I seem to have most of the symptoms associated with Fibro. Does this seem possible? I find myself visiting my PCP, and Oncologist with constant queries. I don't want to think I'm one of "those" people that are dreaming up things. I have many "good" years left in my life with Grandchildren, church, friends, and a relationship with my high school sweetie, but I seem to be always too tired, Would love to hear your input. Thanks
