Hi Mary,
Like you I have been frustrated in the past about the Doctors asking for me to get my BG levels down, at first I panicked and thought it would never happen. Now I just take things as they come, my initial BG level at Jan 09 was 10.3 and now I am 6.2 thanks to meds and diet. I am not to rigorous with my diet, I have a little of what I fancy still, but I do watch how much I eat and specifically what I eat. Try not to dwell too much, do the best you can, set a goal to get down to say 6.9, besides I am told 7.0 is within the limits?
I too am unable to exercise due to having RA so I am limited on what I can do, I would dearly love to go to the gym but with having diabetes and RA I find it difficult to find a gym that are savvy about conditions such as I have. I hope you feel better about your condition soon, I know it's hard to get used to it, but you will.
