I highly recommend you read Dr. Bernstein’s book “Diabetes Solution”. I was on your same boat and it took a DKA trip to the hospital to make me realize that what i was doing was not working. I read a ton but Dr. B’s book changed my life. The first thing it gave me was knowledge about this disease which put me at ease, and then came the control. Now, it’s not magic, it does take a lot of work and dedication but unlike before when I was putting a lot of effort into my diabetes but got extremely frustrated because nothing worked, this time it was different. The work paid off. Life became a lot easier. I controlled T1, T1 did not control me anymore. Go read it, then you can teach your doctor a thing or two about how this disease works.
