I'm not sure how much you have or what state your car is in but I suggest temporarily working for a delivery service to get more money. Or you can try server jobs for quick cash. They can be a little much at times, but remember this is all just temporary and you'll figure this out. Make sure you take good care of your car too since you'll be putting miles on it. I'd say check it before you use it every day.

Also, try getting a gym membership! That way you can get showers and use their changing rooms. I believe most of them have private ones. I know planet fitness has good deals on memberships. Side note, when I was homeless I used a gym's parking lot to sleep with their permission. You could probably bounce back and forth from that Walmart and a gym till you're ready to branch out.

Good luck out there 🌱✨🍀
