Exclusively pumping and breastfeeding

My bundle of joy is 11 days old and still won't latch. I'm producing tons of milk - about 7oz every pump and then my morning pump is between 10&15oz - I am pumping every time she eats with the exception of once at night just so I can get some more sleep in. Since I'm producing so much I'm able to give her only BM and I feel so blessed for that. BUT here is my problem- it is getting exhausting and starting to wear on me. Feeding and then pumping and then changing s taking like 45mins to an hour and it's just a lot. I feel selfish and bad every time I pump because I hate it so much. I have to pump before I go anywhere, when I get home, in the car of they decide to just start leaking. ....ahhhhh! ,😱🐮 is anyone else struggling with this?
