Iodine supplementation symptoms and conditions

extremely depressed after a week of taking levoxyl. Also face is swollen, eye swollen and red and face and eyes burn. These were the same symptoms after taking synthroid after a week. What's next? I am close to being suicidal after having survived lung cancer, surgery, chemo and radiation. To get another primary cancer and have things slide downhill after such a remarkable recovery, I can do nothing but cry after making the decision to have a cancerous thyroid removed that could have served me for years and years since it was such a slow growing cancer. I should have followed my instincts and just left it alone. Now all I want to do is lie on the couch and cry.
