31 weeks anxiety attack

Im not ready, i have nothing for this baby, and even if i did id have no room to put any thing. Literally already living in a tight space and i have 2 kids already plus a stepson. Im freaking the hell out i just want to cry and every time i try to talk to my partner he just says he doesnt know and to stop stressing but im almost out of time. Neither of us are prepared mentally or physically and im just so scared. My baby shower is next weekend but i still have no room to put anything. I dont even have room for a bassinet. Im not ready. I love my baby so much but im already failing and hes not even here yet.😭😭 i have no money to afford a bigger place. God what do i do?!

I just needed to let that out. Sorry for the rant.

Edit*** Going to add that I don't have much to start off with. All I have are my clothes and a bed and dresser everything else doesn't belong to me. We share a home with 3 other adults because my partners ex got evicted from her home and her brother stays with her as he's disabled and then our roomate. We can not afford to move and I have nothing left to "declutter" on top of living in a tight space. The walls are closing in on me and I feel like I can't breathe.
