Baby never stops feeding

I am getting very frustrated, I am breastfeeding and pumping. My 3 week old will feed for 15 minutes, fall asleep for 10 minutes and want to feed again. I get so sore with her constantly attached, so Ill pump 1-2 oz after I've had enough, give that to her and she's immediately still be hungry right after and want to breastfeed again. Hour after hour, constantly for hours and early in the morning when I want to go back to sleep. I can't possibly be making enough and I'm trying really hard not to hate breastfeeding because I know it's best but will this clusterfeeding ever stop?? It hurts, I'm tired, and I'm getting mad which I especially don't want to be. 😞
