I think moving out can be a good thing, especially if you're somebody like me who is introverted and doesn't really get along with their parents. I live in my father's basement and I have aspergers so am often treated like a child, having no privacy and such. I have my own independent decisions I try to make that are hard to live by here such as wanting to eat vegetarian(he's a heavy meat eater).
Moving out can be hard though when you haven't worked for five years and are too intellectually inclined for minimum wage places to even want to hire you(I don't have any proper qualifications to work in anything higher up either). Thankfully I'm getting into subsidized housing soon in the city so I can take some university courses. I grow so bored since I live in a small town, don't work, or go to school.
