Struggling with oversupply

I know I shouldn't have used a pump to begin with, but I'm trying to get off of it and I just can't. I've tried pumping just for comfort but I got a blocked milk duct and almost had to go to the doctor. So I pump because my baby won't eat enough and I get so engorged, but it's a vicious cycle. 😥What should i do? Currently trying to hold off as long as possible, but one breast is so engorged. I'm scared it will get inflamed like the other one was.
