Type 1 diabetes is a sudden onset illness. You don't have it for years undiagnosed, that's not how it works your glasses aren't caused by your diabetes.
A honeymoon period doesn't occur before type 1 is diagnosed. It's the name for the period when a type 1 diabetic has been given some insulin, it allows the beta cells to catch their breath and have a second wind to produce endogenous insulin for a little bit. But that functionality will die off eventually due to autoimmune attack on the beta cells.
If you got seen when you started being symptomatic with thirst and you got diagnosed before you were in DKA they did catch it early. Catching type 1 early is catching it befor you are blue lighted to hospital and very seriously ill or dead.
A hba1c of 98 equates to an average blood sugar of 15. The thing that has had a negative impact on it is the fact you had undiagnosed type 1 diabetes and weren't producing insulin.
