I don't even know where to start. She is becoming very out of control, and I'm scared to death for her.

She is 17, and has next to no impulse control. Doesn't seem to have much regard for right and wrong.

The other night she stole my aunt(who she lives with)'s car, in the middle of a VERY bad snow storm, tried to get her friends to go joyriding with her, and was arrested(but not charged - my aunt didn't want her charged - I am not sure this was the right choice entirely)

She is doing illegal drugs, not often but still doing them.

She is taking effexor XR and adderal but grows more oppositional and defiant every day and more out of control. she constantly curses out my aunt, sometimes hits her, and is very mean to family members.

What can we do to help this poor girl get back on the right track/protect her from herself and others?
