Hate breastfeeding, want to formula feed

Kelsey
I feel so guilty and I cry a lot because I hate breastfeeding. My baby is a week old and is up every hour to eat and I cannot get more than 45 minutes of sleep at a time. It has caused a great amount of postpartum depression for me and I feel as though I can't enjoy being a mommy. I want to switch to formula so my husband can help but I feel so guilty and selfish. Anyone else having a  hard time? Any suggestions?
