Glad you’re ok! Not a fun way to start the new year.
The best way to lose weight, in addition to exercise, is eating a low carb diet. Lots of discussions here about low carb you can search, including this recent one Call Out to Type 1 Low Carbers! https://forum.tudiabetes.org/topics/call-out-to-type-1-low-carbers
Jenny’s site & her book are wonderful http://www.bloodsugar101.com. It helped me a lot when I was diagnosed.
