Feel like a bad mom

I'm 4 days pp and I am so damn in love. I'm not depressed or anxious or anything but happy. I've been pumping my milk but I don't know how much longer I can take. I'm fine with formula but I know it can get expensive. My boobs are killing me almost all day. I want him to be healthy and have breastmilk but I hate pumping. He has a bad latch so I don't nurse. pumping hurts and nursing hurts.

I don't know what to do. I really don't know what to do. I feel so pressured to give him breastmilk. We have a doctor's appointment on Tuesday so I want to bring it up but idk how I'll last until then. It makes me feel like a bad mom. I hear him cry when he's hungry and I want to cry cuz I know I'll have to pump. I just dont know what to do 😭
