I have some experience with type 2 and gestational diabetes. I want to offer some encouragement. I lost a great deal of weight and my doctors tell me there is no sign any more in my blood that I have it or indeed ever have had it. The weight loss 'cured' me-or at least it has put me in a very long term remission. My first two pregnancies were SO high risk, gest. diabetes, pre-eclampsia, I spent months doing the testing religiously while I was pregnant with my 2nd. My third child was born 10 years later, my mid 30's(more high risk generally) and I had NO risk factors happen-we kept a very close look-it is rare not to get it the 2nd time after one with diabetes(actually had it with the first but the docs missed it till baby was nearly 11#!!!) I had my first easy pregnancy (had anemia and nearly, but never fainted a few times)and it was my 3d c section, I was 'old' and had had two very difficult pregs. Losing over 100 lbs changed everything (actually had had 2ndary infertility till I had lost the weight-could never get preg before after the type 2 kicked in a few months after 2nd daughter was born)
Do whatever it takes to lose the weight, your life will improve dramatically in any case! And contact your local diabetes association and beg for some proper training. They will find you someone, I think. The training is really important, and follow up by a caregiver keeping attention to your blood sugars is very important.
Take care of yourself-you are the best gift God will give you-and precious! God bless.
