Am I a bad mother?

I love my child to pieces but I absolutely hate breastfeeding. I have to use the pump and it is so painful and inconvenient. I can hardly ever do it as much as I need to because most of the time I'm too busy with the baby to be able to pump. So long story short my boobs get sore until I'm at the point of tears and I get very upset because I can barely pump enough for a feeding after pumping three times. He usually gets breast milk once a day. My child is two weeks old and I'm considering stopping the breast milk. Am I a bad mother for considering this?
