Was type1/3c, now told I might be type 2

If you have type 2 you may be able to control with lifestyle changes rather than insulin injections ... have they done a c-peptide or insulin test to confirm you are producing insulin in the normal range ?

Type 3 C is a little different as it's caused by trauma to the pancreas, whether it be drugs, injury or illness. Type 1 actually has antibodies that destroy the cells that make insulin. So in type 1 you damage the cells that make insulin, but in type 3 c you have damage to the pancreas that result in not making insulin. Same result which is why it often falls under the category of type 1. A type 2 makes too much insulin to make up for being insulin resistant.....sometimes losing the ability to make enough over time although that supposedly is in less than 6% of type 2's. A type 1 can can also develop insulin resistance.

I don't think what you are describing fits being a type 2. However the pancreas has been known to recover from said trauma and start working again in various degrees? I don't know a lot about it, but this gives a brief description of what they refer to as secondary diabetes, which is diabetes caused by another medical condition.

I’d just add that type is not defined by whether you are using insulin or not despite some people believing this. Although type 1 will always need it, other types may or may not need/use insulin without it changing the type they have.
