>>21711112You will need a car, you do not want to be homeless without a car no matter how bad things are with your mom right now. Just take advantage of having a roof over your head and save up as much as you can to get a decent sized car or old van. If you can get a manual transmission, you'll have less chances of it being stolen by retarded nogs.
Do door dash or ride share for quick cash, invest in a sleeping bag so you don't have to keep your car running during the cold nights to stay warm. Park in Walmart parking lots of find remote areas near you
You can get food from food kitchens or churches and pocket planet fitness is like 10 bucks a month and you'll have access to a gym and a hot shower.
As far as your stuff goes, you'll need to sell whatever isn't necessary. Storage units are expensive as fuck, I lucked out with having an abando that I have keys to to store my big shit but my mom is only slightly insane so I'm still tolerating it for now.
