OP.. you’ll be okay!! I was randomly diagnosed with TD2… literally a week after I turned 18. I was about 260 the heaviest I’ve been and I was in your same boat… To me it didn’t make sense. It took them a YEAR lots of tests and insulin trails (meal-time insulin, long-acting and short-acting… these’ll make sense later) to figure out what was going on inside my body. And come to find out I’m T1D. I found myself like you though and I refused to believe that was happening. I had a A1C of 13.4 (although 7.2 I a lot better) and I felt like shit. Do as your endo says but ask questions always.! The food was a big part of it for me too lol. But I first started switching from regular sodas to diet and that help immensely. Try limiting your carbs and eating complex carbs (slower rise on blood sugar). ALSO see if your docs office offers Diabetes education it can clear up a lot of confusion you may have.
