does anyone else feel guilty & a bad mom for giving there child formula?

i gave birth monday & was so dedicated to breast feeding!!! she latched but not correctly. so nipples became horrible. started pumping, then she got jaundice. her feedings needed to increase so the hospital suggested doing formula as well. so i did.

came home thursday, did pumping & formula but realized i didn’t know anything about pumping as much as i thought i did. it’s exhausting. i would feed her, wait til she is sleep then pump, before i knew it it was time to feed her again & i just never got time to sleep or anything.. i don’t wanna say i gave up but i decided to just go with formula.. for now i’m doing the regular Similac but going to do happybaby soon because it’s similar to breastmilk. has anyone tried it? has anyone gone thru this?
