LW2's friend is probably right, and for all we know, gave the advice in a civil way, but the mother took it the wrong way because SHE TOO  has "psychological troubles." Her daughter has mental troubles (small wonder), but who's raising the daughter? My takes is that the only sane one is the friend, and the mother--who has issues--not surprisingly freaked upon hearing some helpful objective advice and calls it abuse! That she fails to mention the age of the daughter also shows she's inept. The age is very important I'd think, for Amy to have perspective to give her best advice.
