Well both my parents control me, plus a sibling. So I'm pretty much caged in. One parent and the sibling are overly aggressive, and it's a major task to overcome and to reason with them. My one parent probably has a mental illness. And becomes incredibly angry at any behaviour deemed reckless, like going to a store and buying a soft drink no one has heard of. As an adult this type of behaviour has little effect on me, but as a child it totally cemented my view of being a puppet of someone very harsh and cruel. Even to this day I don't think that feeling has warn off. That harshness of control damaged me immeasurably as a child.
Did this play any role in giving me my social anxiety? No not at all. I would still be shy and insecure even if I had more "normal" people around me. What it did do, is make me terrified to make a mistake, no matter how small. And it made me afraid of doing anything "reckless", which in reality is not anywhere near being that way.
So yeah, life sucks when you have controlling people around you. And if anyone thinks that moving out, will help my position, then I can tell that won't happen. I will still be a possession of people, no matter where I reside.
