By no means am i asking for a diagnosis. Just some advice. 


so my daughter has always had some sort of issue. Ever since she was a child she’s been lying about serious things like r*pe , ab*se and for some reason being Ariana Grandes cousin (that lie has stopped now). Now she has actually been through both things as her older brother abused her as a child bc she used to be a boy but always claimed she felt female. and when she was 9 she was infact r*ped by one of her classmates but its always been brushed under the carpet as “they were young”. she’s always had a lying problem and a significant need to be at the centre of attention. now for some time she has claimed she “wants to die” and i have seen scars and cuts over her arms and thighs. she’s 15 now and id say for the last year and a half maybe shes been angry. so so angry. but last night she acted out in a way ive never seen. she trashed the entire house , punched her dad alot and pushed him and said to him “i dont fucking like any of you. you make me sick you could all kill yourselves for i care i cant stand you all” her older brother then came in and pushed her away from her dad and she punched him so hard across his face his nose broke. he then called her insane so she pulled a knife out on him (a steak knife i believe) and said “you wanna see insane? you should be terrified” i didnt know if she had intent to use it but she didnt. he then said to her “you belong in a ward” she then pulled her skirt down and cut her leg and said “the ward wont help me in invincible”. she also has an addiction to marijuana and keeps stealing hundreds of pounds worth of it off him and taking money from us all. what do i do?
