Maybe just be incredibly glad that your dad knows TTATT? She's his problem, not yours. He will likely run defense for you if she ever decides to try and shun you.
As far as moving goes, dude... Definitely. Maybe even make a short temporary move, have your cards sent there, then take off to where you really want to be? You don't want the elders in your new home to even know who you are.
Shoot me a PM with where you plan to go, if it's near where I am perhaps I can be of assistance.
