Is it okay?

Hi mummies, im a mum of a 2 month old baby. And i dont breast feed since i gave birth cus it was a tiring process for me. I’ve been stressing out about people telling me to breastfeed bla bla bla. But i didnt cus nobody supports me at home. I do all the work, i take care of my baby, i do housechores, i barely have a full sleep cus its all on me. Please tell me its okay not to breastfeed, cus its irritating wherever i go, ppl tell me its better fo breastfeed WHICH I KNOW!
