(Oh, God,Janet. I am so sorry)
Dotty,
Janet is spot on about going to court. Take the documentation. When questioned, answer ONLY the question. If they grant an RO (and, frankly, I think you should have one against HER), accept and obey it.
You have two other kids. Use your energy to work on your own life so you can be there for them. It doesn't mean you don't love your estranged daughter, but it does mean you love her enough to accept her choices.
In the parable of the prodigal son, the father does not go looking for the son. He does not try to stop the son's foolish behavior. But, when the son sees the ight and returns, the father shows him unconditional love.
Just remember that unconditional love does not tolerate abuse.
