My DD has lots of problems - caused by MH/substance use. Also our relationship has been deteriorating over the last 2-3 years. Officical diagnosis hasn't been made (yes, she has been seen by lots of people including CAMHS), but from day to day she is getting more aggressive, resentful, blackmailing (i.e. I am going to destroy this family, I will do this (trash the rooms etc) again and again) and quite frankly I'm exhauseted. Does anybody have similar experience? I know I should set the boundaries etc.., but we are NOT in that sort of level any more. ANYTHING to survive so that she is not going to do somehing irreversible.
