Homeless asking for efficient advice! NOT HELP

So I’m early 20s and I just became homeless due to situations I’d rather not explain bc it’s not fun explaining those things but I have a bag with everything I need from clothes, toothbrush, deodorant, etc so I have my essentials except for a car and home. I can survive outside on my own find a gym to wash myself, laundry mat, etc. it’s just now it’s getting cold and i cannot be outside without freezing. I just slept in an old car that’s broken down the other day and it was still freezing I was using a lighter to stay warm. I’m not sure how long enough that is sustainable because there’s only so much things I can fit in my bag it’s pretty full. If I had 5 blankets I’d be fine. But the fact I have no where to put my things because I don’t want them to get stolen is kinda the problem and it’s not like I’m just surviving to stay outside. I HAVE A JOB! But how the hell do I pay for Ubers? My phone bill, hygiene products, and supposed to build my credit for an apartment or house? It’s a loop and I feel like I have to make sacrifices, but what else am I supposed to sacrifice when I don’t have much. I just recently stopped paying for my phone bill so now I’m using WiFi wherever I can get it so I can save that much more towards getting an apartment but my credit is also bad so getting approved isn’t the easiest thing ever. I just recently received an interview to another job across town, which I will go to but that uber is gonna be one hell of a ticket daily going back and forth from two jobs. Not only that but one job is during the day and the other is during the night and i definitely prefer to work at night since it’s been so cold, but 9am-5pm to a 9pm-5am doesn’t leave much time for sleep. I plan on going to college in February I just need a cash car I can sleep in or something to shake. I’ll be fine in a car it’s just that I’ve been through multiple cars already and all engine failures to where they are all unusable and I’m back at square one. I can’t seem to find a reliable cash car and even when I used my credit to finance a car they sold me a lemon and now that’s some thing I have to deal with on my credit. I’m just looking for advice and a word of encouragement or if anyone was in the same situation I’d love to hear what helped you get out of it. I’m big on energy around you influences you so that’s why I stay away from section 8 and homeless shelters and the shelters won’t let you in past a certain time or if they are full. So I just look for stuff that isn’t too far preferably from my job so I can walk, but I haven’t been saving much money. (I don’t any drugs at all! I rather stay away from them to be honest, I barely eat not because I can’t just because if I feel like I don’t need to I’m not gonna waste money and do it anyway. I can eat every other day and be fine, but when I do I prefer fruits or something that I feel like gives me energy an life)
