Hi Ellie... you do have your hands full with your D's situation. Hang in there. Things will get better.
I've used a Doctor of Chinese medicine for almost 5 years now to help control my TypeII diabetes. The herbal tea is gawdawefull but it works. My D first took me to see him.
About 8 years ago my D suffered from a terrible skin rash. She saw every specialist in her city, none of whom could help. Oh sure, they used various prescription drugs but nothing worked. Finally, her doctor referred her to a shrink. The shrink was the one who took her to see Dr. Zchou ! Three weeks, and daily herbal tea later, the rash was gone.
