C-Section or Normal Birth when High risk?

This is my second pregnancy, my first I laboured for 48hrs and had to have a Caesarean, now this second pregnancy I'm 343 pounds, diabetic and trying to decide what is best to do for me and my baby. I had so many issues with my first pregnancy cause I laboured for so long but my recovery was quite good after my surgery. I'm scared to labour for so long again due to my high risk problems 😔 so now the mid wives are asking me what I prefer but is caesarean safe whilst being at a large weight? Is there anyone out there that has had a c-section and around the same weight (size 26 & 155kgs) any advice would be greatful thank u 😊
