Would it be a 180 for you to take the reins, forge out a plan to deal with your D's issues and implement getting her the help she needs? You do this for yourself and your D, Angel, and I promise that some of the anxiety you're feeling will diminish.
Your H may not be in any kind of position, at this time, to deal with what's going on with your D. Generally the MLCer is so wrapped up in themselves to really give much thought to anyone else.
You are the sane parent right now. Take charge of this and keep your H in the loop w/o ridicule or blame.
Whatever your D tells your H is between them.
Does your D have access to a computer with internet? If she does, I would check the history and find out what sites she may be visiting.
