Hi mummy, don't worry too much. Not pumping out much doesn't mean you have low milk supply. Do read the article to look out for other signs to know whether your child is feeding well.. https://kellymom.com/hot-topics/low-supply/
It doesn't sound like you have low supply, I also pump about the same amount. The more you latch, the more supply will come. Maybe you can try taking a few days to just lie on bed and latch baby as often as possible the whole day?
Pls don’t be guilty for not able to breastfeed your baby. It isn’t shameful to bottle fed. I mixed around breastfeeding and formula for my first baby. And now he is growing well. I hope you don’t pressure yourself. :)
You can always eat those milk booster 😊 my supply is also low but I didn’t gave up, i pump like every 2hours.. though supply still not enough so i gave formula milk for backup.. don’t be so stressed out mommy.
Don’t feel bad! Maybe try lactation cookies / oats?
