terrified of planned c section

Bi
So my Dr has decided we should make a date on the next visit to have a c section due to medical reasons😫 
This is my 4th pregnancy 3rd 👶 baby. All previous were Vaginal births. 
But I just can't get my head around it I'm terrified and I'm not sure if it's just the op itself or the longer recovery. I suffer with both depression and anxiety I would hate to flip out the morning of 😳. 
Mums that have had a c section in the past Any advice would be appreciated . 
I need to start preparing myself mentally I have 12 weeks left.
Thanks in advance.Â
