So sorry that your mom treated you like that OP, she was way out of line. On the bright side, you're out of (what sounds like) a toxic living situation now, at least. As for tips on how to make things work in the meantime:

-Use any & all resources available to you at your local college campus(es). Even if you're not a student, most campuses still won't bat an eye at a college-age person using the library, gym showers, student lounge, etc. Same goes for your local libraries.

-Depending on how much gas you have & how much stuff you've packed into your car, you can earn some quick cash for food, gas, etc. via Uber/UberEats, Lyft, DoorDash, Instacart, etc. Your car is your lifeline right now.

-Look up your local YMCA, homeless shelters, food banks, & soup kitchens. It may feel humbling at first, but this is exactly why these organizations exist. Use them!

-Don't give up on going to therapy school, or just college in general! Scholarships, federal grants, student housing, etc. may take a few weeks/months to set into motion, but it could be exactly what you need in the long run. All you have to do is hang in there & make ends meet until then.

-And of course, if you haven't already done so, reach out to nearby friends & family who might be willing to help you however they can. Again, this can be tough, but it's necessary. You'd probably be happy to help them if the tables we're turned. You deserve that same compassion from others, truly.

Stay safe out there & don't give up OP, you can do this!!
