33 weeks and want to be done being pregnant

I know my son has a few more weeks before he could easily be born and not need any medical intervention afterwards BUT I am so sick of being pregnant. I can't lay or sit without my back and ribs hurting. Can't sleep. I get maybe 4 hours of sleep and everyone says I should be sleeping as much as possible before baby is born but it seems impossible. He kicks my right ribs so much and it makes everything hurt. I've been leaning colostrum since 18 weeks and I soak through thick sweatshirts EASILY. How did anyone get through these tough times? I've also got severe allergies, horrible migraines, extreme nausea and horrible heart burn. How do I get through this? It's hard to distract myself and pass the time when I'm in pain 24/7. I know it's "part of being pregnant" but I'm just 100% done. All of my brothers were born before 36 weeks and they're just fine. I was very late term and I'm scared my pregnancy will be the same. Ugh someone help 😩😭
