Breast feeding to formula helppppppo

I’m giving up on breastfeeding:( my 5 month old has had formula but not recently so she’s not used to the taste, she’s been exclusively breast feed. Every time I give her formula she makes disgusted expressions (🥴🤢🤮), spits it out, and refuses to drink it. I don’t want to start formula cold Turkey but every time I try she just refuses. She’ll drink bm from a bottle, so bottles aren’t the problem.

I’m so done with breastfeeding. My baby is so small I feel like her size and weight would be different if I offered formula. I also nurse a million times a day and yet still worry if she’s getting enough, ped says she’s healthy but I can’t help but worry. She’ll only latch if it’s in a quiet setting which makes it hard if someone in my house is making noise. So over the engorgement, leaking milk, nursing bras, nursing clothes, pumping, nursing a million times day n night. I need a break even if it breaks my heart but I need to stop for my sanity
