text: Wow.  Scary.  From what you said it does sound suspicious.  I'd first talk to any relatives/her friends (hopefully in confidence) to see if they have noticed anything.  If so, do an intervention. There are mediators for that.  Ask a church leader or a private org like narcotic or alcoholics annonymous.  I'd do all that before getting authorities involved - that would be a last resort.\n\nDon't give up and never ever blame yourself. Children of drug/alcohol abusers often do.  DOn't fall into that trap.\n\nBest wishes to you.  Be strong.
