Wtf I’m so exhausted

So I’m battling mastitis that came on pretty quick today. Sweating through my fever and pain. I’m nursed LO who fell asleep at 9:20 ish. Then he woke up about 20-30 min later. Nursed again. Burped cause he gets all kinds of crazy gulping and flailing. I refused to walk him around cause I’m fucking hurting. SO doesn’t step in to help. I let baby cry. I mean he’s laying right next to us. It’s not like he’s in a crib alone. He’s lucky to be sleeping like a pack animal. Anyways I end up trying to feed again then burping. He sort of falls asleep on my shoulder. By this time around 10:20 I start walking around the room cause he’s fat and happy - not asleep yet. He falls asleep. I sit on my bed just holding him cause I heard you have to hold through the sleep cycle. About 15 min go by and I put him right next to me on the bed. He starts crying immediately and flailing. My head is killing me. My body is killing me. I’m all sweaty cause my fever broke with 3 ibuprofen. I flip him on his belly and he passes out. Wtf? I’m going to wait a little bit then flip him back over but shit. I guess he takes after dad being a belly sleeper. He honestly never sleeps on his back and it kills me. He sleeps on his side snuggled up against my boob. I don’t know if I can break this habit.
