About to give up

My son is 16 days. I have developed mastitis in my left breast with a bleb on the nipple. I’m in so much pain I almost want to avoid bf on that side but I push through. I’m not producing enough so he wakes up every hour to feed which is torture. I supplemented with formula and he threw up multiple times. I always wanted to be one of those moms that breastfed until they were one year old but I can’t make it to one month. I’m exhausted. I’m in pain. I can’t do this anymore.
