Csection bt wanting VBAC

Cristian
So since i have type 2 diabetes ( 4 yrs already ) my obgyn said it would b best if i have another csection since im insulin dependent. This is my 2nd pregnancy my 1st i had to have an emergency c section. Only reason im on insulin is cuz im pregnant . When i wasnt i would just take pills for my diabetes . I at least wanted to try for vbac bt i dnt think its going to happen. I just dnt understand what me being insulin dependent have to do with anything if my obgyn didnt say anything about it my 1st pregnancy 🤔...what is ur alls opinion?
