I am very worried about my 13-year old daughter's behavior.

I am her father, she is currently in 8th grade, but I'm not even sure she'll be able to graduate. Even if she does, I don't know how she's going to handle High School.These past two years she's been acting up a lot and getting into a lot of trouble at school. She would fold and staple paper into the shape of assault rifles and other guns. She got suspended for that since the school has a zero tolerance policy for guns. She'd bend paper clips into a straight line and then stab people with it until they bled, this got her suspended again for even longer.At home she'll often say weird creepy things to me like, "What would you do if I brought a knife into your room?" things like that genuinely scare me.For the record, she hasn't been diagnosed with any mental illnesses beyond ADHD, but she is being medicated for it and this has helped with many of her symptoms. The poor impulse control may be part of the things she does but fails to explain other things.Each time I'd try and do everything I could think of to help her, but no matter how much I talked to her, grounded her, paid her to see therapists and psychiatrists, nothing has seemed to make any impact. She'll promise not to do it again, then the next day she'll be right back at it at school.I genuinely don't know what to do. via /r/Parenting http://ift.tt/2eDLDNz
