D.B.
L., I'm so sorry. That happened to me 2 1/2 years ago. I lost so much weight in 6 months that I was afraid I had hurt myself. I had facial pain that made me feel that they were missing a brain tumor diagnosis. I ended up having sinus surgery, and things are better now, though not back to normal. I doubt I will see normal again, to be honest. But I don't throw up every day.
Do you have a rheumatologist? People actually come from different states to see mine - his name is Dr. Carpenter with DuPage Medical in Illinois. It takes several months to get an appointment, but it's worth it. A rheumatologist is kind of like a doctor's "Dr. House". (Without the bad bedside manner.)
I know that your circumstance is different than mine, and I am much better now. I have started exercising, doing a gentle yoga class, and walking on my treadmill. I am well enough to go visit my friends overseas twice a year too, though I am careful and pace myself. I just don't over-commit anymore and keep my stress down. It's a little easier for me because I have teens, and only one at home now.
My internist told me something that made a lot of sense to me. He said that when the body is stressed, or in a lot of chronic pain (which was the case for me), that it reacts in different ways. You sound like me - with not being able to eat, and throwing up and all.
There is a supplement in the drug store for diabetics to drink that keeps the blood sugar steady. It is sold in a little six-pack. I forget the name of it, but you could find it pretty easily. It was talked about in one of the diabetic periodicals, and it has a lot of nutrients in it. Why don't you try that and see if it helps? You don't have to have diabetes to use it. Getting ahold of your nourishment is the first thing, in order to get other things handled.
I hope you can do this. It's the FIRST step in coping with the guilt. I promise you.
