Troubles at home

I have a majorly strict dad that is strict to the point of where I fear to do anything that may even make him shout but I want to get away from this and I don't think anyone understands how bad he actually makes me feel. I have tried to run away from it before, but a friend accidentally slipped up and told him where I was staying and that lasted about until early the next morning, and I have been grounded ever since considering part of the reason was that I was addicted to meth but I'm off it now kind of a thanks to being grounded as I was able to go cold turkey but it's getting to the point where not being allowed to go out the house for so long is actually driving me insane more than it was before and I really want to get away but have no idea how to?
