Quitting Breastfeeding

Is there any way to help your milk flow stop? Or ease the pain while it dries up? I’ve been trying and trying with my daughter and she just won’t latch. She’s on formula and eats amazing on a bottle, but just not the boob. I really wanted to breastfeed, but I’m losing hope and my boobs are SOOOO big, hard and extremely painful. I can’t even hold my baby against my chest or sleep on my side because it’s like two big rocks smashing together 😩 I feel really guilty not breastfeeding, but maybe it’s just not for us 👎🏼
