Diagnosed 3 weeks ago, we still have no clue what’s going on

I went into the doctor after my grandma (t2) noticed I had lost a huge amount of weight, 70 lbs in 6 months.

The doctor tested my A1C which came back 14 This led to my first endo to believe I’m type 2

At the same time they did a whole bunch of bloodwork and when that came back I was positive for the type 1 antibodies

For unrelated reason I had to change endo’s and we still aren’t sure what’s going on with me, his plan is to treat things as type 1, So far my blood sugar has been pretty high, fasting sugar hanging around the 230 range, and it usually goes up to 350-450 after meals

I’d love any advice people can give me and if you want to know anything else, let me know
