poor blood sugar control

My boyfriend was diagnosed 2 years ago with type 1. He does not look after himself and rarely tests his sugars or injects. His sugars are often in the 20’s! Every time I remind him I am seen as nagging and it just makes us fight. My dad is also type 1 so I know what he should be doing. His mum...

Been type 1 for 39 years. Taken off pump as too many hypos. Allergic to lots of different insulins. Now on humalog and insuman basal. Blood sugars random between 1.8 and 33! No pattern. Changed injection sites, now in bum!! Still no better. Anyone in same boat???
