I’m gutted. On the verge of quitting. Convince me not to, please.

I’ve always struggled with my milk supply. After I gave birth to my second I swore I wouldn’t give up so easily and try as long as I could so I can provide for my kids. I started from 2 oz a day to 8 oz in a months time and I was ecstatic. Then period came back and it all disappeared in the blink of an eye, and I haven’t recovered since, a month later, after having my second period. I’m fed up with this bullshit and I hate pumping but I love giving my kids my milk. It feels like my body is mocking me. I have the right flange fit, I pump 6-8x a day, I eat enough and hydrate enough. I take the damn supplements, I eat everything oat related, I drink so much soup im sick of it. Please convince me not to quit because I’m just so close. It feels like my worth is measured in milliliters and ounces and it’s just too much.
