@maddygrace720, no need to feel horrible. It can take some time to get a good rhythm that works for both of you. Have you tried a nipple shield for a while or have your baby checked for lip/tongue tie?
The amount you pump, isn't an indicator of how much milk baby gets when she's actually nursing. My baby gets plenty from one or sometimes both boobs, but when I pump, it's like 1 oz. Don't give up just yet. Pump more in between feedings. At the same time every day, so your body will know when to make more milk @maddygrace720
