It sounds like you fall into Type 1.5 (someone else may correct me on this if I'm wrong).
Basically the beta cells in the pancreas are dying/being destroyed, but some are still functional. As you lose weight, the remaining cells may be able to produce enough at times, because body fat likes/needs insulin, so the less body fat, the lower the requirement for insulin.
But the process of beta cell death is unlikely to stop
edit: welcome to the forum btw, I only joined recently too.
