I still don’t have an official diagnosis .... but I am treated as T1 and insulin dependant on a nasal/bolus regime.
I was 26 when my symptoms started - the usual thirst, thrush, losing weight (1 stone in 3 weeks), tiredness...
My mum is T2 and my sister has gestational.
I had my c peptide done twice - once fasting and once stimulated. One came back low and one came back medium low. It took about 4 weeks to come back
My first HbA1c was 103 and a year later it’s 50. Over the last year I have needed more insulin as the time has gone on.
Hope that helps but if you need anything else, let me know!
