What should I do?

So my little one is almost 6 months old now, my milk supply has definitely dropped a huge amount. We have been supplementing formula since she was 3 months old due to poor weight gain but I still nurse her right before bed and first thing in the morning. I love the bonding time but I hate how breast feeding makes me feel. I get a brief feeling of depression or sadness when my milk lets down and it’s not fun. I actually anticipate it now. I’m not sure if I should just stop nursing all together or if I should keep trying. I mean I just don’t feel

Ready to completely stop but I also am

Not a fan of it. Arg not too sure what to do. Anyone else going through this?
