no doubt homeless is the last thing one wants to aim, no doubt. I'm not sure you could handle that, Emily.
but you can get a temporary room in Nashville, then a roommate and a job, you don't have much savings but enough to give it a try, as I'm certain you can get a job in Nashville if you are really motivated to do so, and much more opportunities in Nashville than where you live.
After PMing with you, I see to what extent your negativity can come simply all from the people you live with. You don't own your life. You can, you're intelligent. It's not normal that your parents control your life that much at age 24.
that's my opinion. Get a job in Nashville, rent a cheap hotel room at first. You can own your life.
