Welcome to the Forum!
We are glad that you are here, but wish that we could have met under better circumstances. That being said, read all that you can on your condition. Education is the key. The information will be overwhelming, sift through it, make notes and go back and read the noted items.
Check into carb counting, see an endocrinologist and a nutritionist. Find good ones and put them on your Diabetes Team! Good luck with your control and management.
