Zoso...I am so very sorry that this has happened...and you are right...each one of our addicted loved ones affects their own loved ones and those who love them.
Stay calm and hugs are going out to you (that is my 'go to' as a mom when just don't what to say or do...)--given her young age and your relationship with her...sending deep prayers for her HP to work with her very quickly...although I know it is not something any of us can control for her.
