Have you ever tried telling them exactly what you wrote here? It seems like you could phrase things in such a way that it isn't correcting them, but letting them know how bad you feel when they say certain things. I thought what you wrote was very factual and respectful towards your parents, even though the things they are saying are extremely hurtful, especially the part about not trusting you on a job. How is that motivational?!

It's great that you are taking steps towards straightening out your own future, even without their explicit approval or support. You probably *will* feel better once you have a job (and can afford to live somewhere else!), but it can be hard to find the motivation to find a job when you're depressed!
