funny how anxiety makes us avoid so many situations but then just creates more anxiety for us in avoiding those situations. sounds like you were bullied into something you didn't want and your sisters are enjoying it more than you are. you get to live with the daily anxiety of it. weigh that daily anxiety of living in a home that is too much for you against the momentary anxiety of standing up to your sisters and decide which you would rather have. sure it will be briefly intense while getting out from under the house, but then you will be free. wont that be worth it? think about it. take care.
