What should I do? I'm like a 12 year old.
What do you mean you're like a 12 year old?
I feel like a child, I don't feel I can go out freely
As an adult you should take charge of your life and be responsible. Adults are expected to be able to control their own movements.
There's nothing to do here. There is no point of going out why not stay home.
It seems you feel restricted in your current environment even as an adult. Although there may not be many places to go, it would be best to get out and interact, rather than sit around feeling like a child.
