Welcome to the forum. I was diagnosed four months ago (type 1 like you) and this has been an incredible place to get help and support. This forum helped me get my a1c down from 13.2%/121 (depending which measurement you use) to 6.0%/42 in three months.
Are you able to elaborate a bit more about your situation?
Was your 72 a1c a surprise or did you expect it to be that high?
Have you always had high cholesterol or is this new for you?
You mentioned you gained 2 stones, but how much did you lose before your diagnosis (if any)?
