Need Medication For Aggressiveness And Violent Behaviour

I have had a surreal year with my 14-yr old daughter. Ever since I attempted to confiscate her iphone about 6 months ago, she has seemingly turned into a someone I don't recognize. That first day when I attempted to take the phone away, she physically attacked me to try to get it back. I called the police. Since then she has been physically violent with me on several occasions. All of them have been when I have attempted to take something away from her as punishment (her phone, her makeup which she is obsessed with, trying to look in her book bag for missing progress reports, etc). On top of her being physically aggressive with me, she turned the tables and has made false claims that I physically hurt her. Three child protective cases have been brought and dismissed because they have been found to be baseless. She has threatened to commit suicide when she didn't get things that she wants. She stole my mother's credit card and charged over $2000 in products on amazon (perfume, makeup, coutour dog products for a dog she doesn't have). She has been hospitalized three times for suicide attempts. The last time she claimed it the hospital wouldn't even admit her because they too could see she was manipulating. The ER psychiatrist even told her so. This weekend when I confiscated items from her room she had stolen, she proceeded to destroy her room and then told her caseworker that I did it. She is currently in intensive home therapy and on medication but nothing seems to be helping. Her case worker and the ER things it is all behaviorial. But is that possible? Certainly there is some mental or psychiatric problem causing all of this. She was normal before a year ago. In her head she seems to be equating my touching or taking her things with me doing her physical harm. Is there such an illness/phobia that would explain that? Please help! No one seems to be able to help me/us.
