Now that's some bad parenting. But you are going to need to do something if you don't eventually wanna live on the streets. Your mom isn't going to be there forever, and doing nothing for longer will make it more difficult.
And if it's her that's keeping you down and disfunctional, I can tell you from experience its 1000x better to live alone.
This sounds like getting a job thrown on your lap, unless you really hate it, go for it. You can always use it for some experience and go for something else later.
