I'm just going to fixate on one thing you wrote that really resonated with me. Your parents don't want you moving out unless you're married. My family isn't that different. My father's cool, but my mother is very over-protective. I managed to move FAR away (1600 miles or so) and rarely come back home.
Do you have a job/career-path? Do you have a means of slowly planning your move from home? Maybe I'm just projecting, but I think it's important to eventually get away from your parents and have your own space. And it's bad for your mental health if you're living with people who have different communication needs.
Let's say you have an issue with over-sharing. Can you commit to a day of not talking to anyone, just to see how it feels? I talk to a lot of friends by phone. Sometimes I think I have an issue with needing to just talk/share too much. I try to tamp it down by writing in a journal once or even twice a day.
