She wants her mom back. She doesn't want to have to take care of you. If you have a street puppy attitude you will be treated like a street puppy. My daughter was the same way--it's very normal. The stronger you get the greater you will see a change in her.
She sees you in herself--every daughter does. And if she sees you going wackadoodle she wonders if the same can happen to her. No child wants to take care of their parents ESPECIALLY AT 19.
The greater your work at self healing and getting stronger this will turn the tide with your daughter. It did with mine and now we are closer than ever.
hope this helps
