Hi Catherine,
Of course we want you to do your best to get your weight down and for you to feel better. March is a very short time away when it comes to long term weight loss however. Even pretty strict diets really acheive half a pound to 2 pounds weight loss a week. Be aware that if you want to have another baby you could well need insulin during the pregnancy. There are also newer drugs called byetta and victoza which are not insulin but are injected. They do seem to help weight loss in type twos a lot.
Many people think that jags are the worst thing about diabetes but honestly you will get over it very quickly.
Keep positive. Your health care time should listen to what you want and help you get it.
