I am sorry to read that you lost your husband. Maybe you got better because you knew you had to for him (if it was not sudden) or for yourself to take care of you business or both!
Manic depressive maybe? I don't know but my father-in-law has chronic fatigue syndrome, and he sometimes mopes about and then the next second is wired for sound. Don't be scared,
just from reading your post I get the feeling you have many friends who will help you out in a pinch, though you do not want to burden them. Just make sure you don't put it off too long if it recurs as the longer you are in it, the harder it is to get out.
As far as physical symptoms caused by the mind, my depression does and I feel strongly about it and have some very good examples. It most certainly directly contributed to 2 back surgeries, the latest only 3 weeks ago. I also this year in June, after I left work with an inability to cope at my managerial position I held, had a saliva gland of all things get badly infected to the point it was surgically removed. You have 3, so you can get by with two. I also had a narrowing of the esophagus and a hiatal hernia that were repaired while depressed, but still working at my job.
None of my dr's connnect the dots, but I feel when your mind is weakened, so is your immune system and other PHYSICAL attributes are susceptible to impairment moreso than when your mind is totally well. Am I a Dr? No, but I play one on a message board
. I do know my body fairly well and have self-diagnosed, with a great deal of accuracy, most of the issues I have faced, nearly 10 major surgeries over the past 20 years of my 38 year life. I even knew it was my saliva gland that was the problem, despite improper initial diagnosis of a lymph gland. The ER Dr. was kind of PO'd as he said something to the contrary before and I told him no a couple times, it is the saliva gland. He had the, "I am the one that went to school for 15 years, I think I know better."
So my lengthy soliloquy basically says I do not know what you have, but your mind can control/lose control over physical things, allowing if not causing true illnesses. I'd argue that with anyone as I am a very good example.
I too wish I had found this site sooner. I really needed it, though, before Al Gore invented the Internet.
