Breastfeeding has me drained out… feeling guilty for wanting to switch.

My baby is 4 weeks and 3 days.. I’ve been breastfeeding this whole time. People have told me it gets easier but it seems like it just as hard as it was the first time. Especially at night. At night is when I loose it and feel like quitting. I cry every night due to no one being able to help me, I feel like he doesn’t eat enough either at night, like if I don’t produce enough. I want to start him on formula at night and mornings but the real problem for me is that no one can help me feed him since I breastfeed, most of the reason I want to switch is so I can get help feeding him so I can sleep more. But I still wouldn’t get enough sleep since I’ll still be the one who has to wake up and feed him at night and that’s when I want to sleep the most… It sounds horrible and I feel horrible and guilty for not wanting to breastfeed anymore… any advice?
