So frustrated

I just had my first on the 3rd and got bad lactation help at the hospital. By time I got home and started pumping my baby was used to formula. Got pumping and my supply in but it’s so frustrating to pump. I got in with a better lactation consultant but it seems my baby will only latch when she’s around. I’ve tried every position possible and every time he just won’t latch. He just screams and pushes my breast away without even trying. I’m at my wits end and just not doing good mentally. Hubby has been trying to be a help but he doesn’t quite understand what I’m feeling and going through. Every time my baby cries I cry. I’m freaking out and constantly thinking I’m a bad mom. I mean he stays fed and changed and warm but I just feel like none of that is good enough
