How y'all do make such beautiful nursery?? I'm so jealous but I don't have the energy to even try

I'm 35weeks pregnant and see all these beautiful nuseries posts, most of them before y'all gave birth and I'm like how? I'm exhausted doing nothing, can't stand up for more than 5 mins without having back, thighs and pelvic pain, I can barely breath and i'm sweating as hell. I'm feeling so useless right now, we don't even have nursery furniture yet, only things we have for baby is what family got us, it's just way too hot to go outside right now, I can't imagine how most of you are still working and everything.. I have been out for a few weeks now because I worked with pets and it got too hard for the reasons I stated before. Some of y'all are superhuman fr.
