Breastfeeding failure

I could use some words of encouragement, mamas. I'm officially giving up on trying to breastfeed my LO. I have spent five weeks of pumping all the time, taking Reglan (and dealing with the side effects), talking to lactation consultants, spending money on possible solutions that didn't work, and stressing over how I just couldn't produce more than a couple ounces in an entire day. I had to stop taking Reglan because I think it was partly responsible for the PPD I developed, and I pretty much dried up.

I feel like a failure as a mom and keep going back and forth on whether I should keep trying, but I think for my own sanity I need to pack the pump away. I know formula is a perfectly fine alternative but still feels like I'm not providing my LO with the best...
