Feeling horrible

I am extremely tired. Extremely hungry. I feel weak. And just overall I feel like crap. I’m 36 weeks. Is this all that comes with the third trimester or could something be wrong. I can’t even sleep at night. I get horrible wrist pain throughout the night. I’m itchy. But it just feels like it’s super amplified and feel more tired/hungry/sore/weak/etc than I should be. Any advice??

I’m almost there but I’m terrified of baby girl showing up because if I feel like this, idk if I could go through labor feeling this weak.
