I think your family has to be strong - but not violent with her - with an amount of understanding - but not pandering to her. No-one should tolerate being threatened or bullied in their own house, by a member of their own family......this could break down into a really nasty situation...I sincerely hope not. If she won't seek proper help of her own accord...dare I suggest Section 2 of the mental health act...wielding a knife at one's parents is probably reason enough for her to be detained to be honest...she's not a teenager.It has seemed that way, shes bullying them and when it comes to me I dont take it so she throws a wobbler. I do believe she needs bringing down a few pegs Im just waiting for her to start on me and not provoking for her to blame it on me.
Apart from that yes she's smoking some 'legal' version of weed called Skunk but her b/f smokes weed as my mate knows him. He's an unemployable worthless div who does nothing else with his days apart from play console games and smoke.
She needs attention just I dont think a counsellor is going to have the effect which is needed, when she can say what she likes unchallenged.
Your all right to an extent, just wondered if anyone knew if there was a process for getting such people 'looked after' as it were.
Regarding skunk...it's lethal! It's (I think) now being proven to be linked with psychosis and psychotic outbursts...
See these links....
Best thing would be that she was no where near that BF...who knows what other things he has his fingers into..?
I wasn't squeaky clean as a youth....but I knew where the boundaries lay...she doesn't I'm afraid. Saying that, she does need support in some way - not aggression.
