Hate Breastfeeding..

Aubrey
Have been breastfeeding/pumping for my little guy for five weeks now. And I still hate it.. My nipples aren't sore or cracked or anything. I just hate how engorged my breasts get and now they are ginormous literally my DDD bra doesn't fit.. I hate the smell of milk and leaking. I feel like it takes forever to breastfeed vs. bottle. 
But I feel selfish if I were to quit and give him formula.. Also the cost of formula. 
Any advice?
