Don't have anything ready :( super stressed

Idk what to do. My son will be here late November and I barely have anything. I have a car seat, a few onesies, a 2 pack of pacifiers anddd yea that's it. My neighbor bought a stroller and said she got a bunch of clothes. I still need so much but money is very tight. I mean very tight. Like after paying bills this week were left with 10 dollars. Yea I'm not kidding. My fiance works full time and gets overtime when he's allowed but it's not often. So he brings in 300-350 a week. We have to put away 250 a week for rent right now bc my landlord is cracking down on us being late. We have a broken car, don't know what's wrong, don't have the money to find out what's wrong. So I can't work. There's no one around me hiring. I'm struggling from depression /anxiety and I'm just freaking out. What can I do?
