Need advice on finding a new place to live

I'm very scared about what the future brings for my fiancé and I... We both recently became homeless and are living in a tent at a campground. That campground is going to be closing for the season soon and we have no other choice but to sleep in our car... These winter months, they're not going to be easy living in a car... I miss feeling secure... I'm just tired, I don't want to stay in a shelter where I run the risk of my stuff getting stolen or not being able to sleep with my fiancé. If I could get us out of this shit, I would in a heartbeat, but nowhere seems to want to hire us and we were doing door dash til we got pulled over, now we can't drive legally because my fiancé got in a car crash in December and they suspended his license because we can't pay the ridiculous insurance claim. So I have to get my license despite having severe test taking and driving anxiety just so the cops don't pull us over again. I'm tired of the "help" I keep getting offered, I'm not helpless, I just want someone to listen to me, and offer words of advice on what I can do to stay warm, what I can do to keep food from spoiling, shit that people have actually found helpful... I miss having a home... I miss having pets... I miss feeling like a human, instead of a wild animal that nobody wants around them...

Stressed Out and Overwhelmed by Moving

I'm short on rent. Like really short on rent. Normally I have rent saved and then whatever I have to take from it gets paid back with paychecks throughout the month, only I haven't been able to work the last 2 weeks (unexpectedly). So I haven't been able to pay that money back. Now I have to ask either my sister (who is living off of money my grandparents gave for med school) or my parents. Both parties would be incredibly disappointed. Both parties are likely to say no. I don't know what to do. I have nowhere else to turn. No one else to ask. I know I put myself in this situation and I'll need help to get out of it. I could explain exactly where the money went but it would be the same level of disappointment as if I told them I spent it all on drugs and gambling. They will never understand that it was spent on bills I'm still behind on, gas, and food deliveries because I've been so depressed/overwhelmed that I havent unpacked (moved in April) and I have fruit flies so bad I can't go near my kitchen to even think about cooking. How do I ask? Is there some sort of assistance program I don't know about? What do I do?
