Lung cancer surgery symptoms and conditions

started 10 mg in 1998. was controlling everything ok. In 2004 developed weakness in both legs, started slurring words and eye trouble, went to several doctors then in April 2005 had to quit work as I was just to weak. That was at age 54. Finally a neurologist diagnosed me with Myasthenia gravis, and lambert eatons myasthenic syndrome. Had my thymus gland removed, which is supposed to put disease in remission, also had small cell lung cancer surgery at same time. improvement did not come and the drugs for myasthenia only made me sick. started having chest pains and doctors ,.found several blockages in my heart ,still do as to weak for surgery, cardiologist took me off of lipitor and I seem to have stabilized, still have trouble with short term memory, and vision, and really weak

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.
