Many people have tried to help her in the past few years and she runs away and does what she wants the first chance she gets. You cannot force her to take care of her mental health any more than you could force someone to take care of their physical health. One lawyer described it in an article I read as "she has the right to be crazy". That may be a crass way to put it, but it is the truth.
Right, but that's because she is mentally unbalanced. Like I said, it's not like she is on drugs and willingly doing the behaviors associated with that. Her brain is telling her people are out to get her, so she acts out in the way she thinks is appropriate. She runs away because her brain doesn't tell her the "right" way to act. The whole thing reminds me of that family that was in the news a few years back that have a young girl (like six or eight) who is schizophrenic. They have two apartments in the same building because she is afraid she will hurt her brother, and the parents take turns taking care of her. I have no idea what the answer is, but moving to Texas does not seem to be the right one, unless they plan on flying out here on a weekly basis to check in on her.
