Bad mum for not wanting to breastfeed?

I’m pregnant with my first and I am really not keen on breastfeeding at all. I’m having a bit of a tricky pregnancy and to be quite honest I just want my body back once the baby is born! I know that formula can never replicate the benefits of breastmilk, but I’ve heard nothing but horror stories about breastfeeding (on Glow and from friends). This can be a touchy subject as I know there are lots of mamas who want to breastfeed but can’t- am I being a really terrible mum by deciding not to?
