Ending m breastfeeding journey

My baby just turned 1 on the second and I’m thinking about stopping. So happy that I made it to one year but it’s getting really hard for me. Everytime she feeds my nipples hurt so bad now. I’m working 2 jobs and I’m just exhausted and now she’s starting to bite I’m just so over it. How did y’all stop or any recommendations on how to? She doesn’t like whole milk she gags when I try and give it to her and I feel that’s she’s too old for formula now. I’m so lost any tips y’all have please comment them below.
