What is the nutritional difference between breastfeeding and pumping?

I feel a little guilty saying this but i hate the feeling of breastfeeding. It makes me feel so uncomfortable and it makes my skin crawl. I dont like the feeling of mt nipples being pulled and sucked. Even before when i was trying to induce labor after being 41+weeks pregnant, i tried nipple stimulation for 10 seconds and broke down in tears because it made me very uncomfortable. My baby is 2 weeks old and hes eating great with a good latch. But the feeling of breastfeeding makes me feel so uncomfortable with my body. I dont feel like myself when im feeding and i feel a bit depressed. I want to try to feed as long as possible because i heard thats whats best. But im thinking about trying to pump instead. Any advice?
