I don’t have a girl with CAH, but I must say that my son (CAH)  has times where he becomes very aggressive and if it’s not his way it’s the highway.  It’s not usually with adults although he has tried to pull it with my husband and myself.

What we have begun doing is having him sit down and write a letter to us explaining why he behaved the way he did, what he will try to do next time to make it better and how sorry he is that he behaved that way.

What this has done is given us a great insight into what is going on with him and in his mind when his assertiveness/aggressiveness gets triggered.  It has opened the doors of communication and we find that we bond just a little bit closer each time.  It usually ends up with a few tears (on both our parts) and an appology or two.

Good luck.

P.S.  Danny, I have taken your advise on talking to my son and letting him know that sometimes it is the CAH that makes him moody.  I ask him if he is going to let CAH win each time and it helps him to rise above and laugh at himself.  It doesn’t always end that way, but for the most part he does feel empowered when he is able to shake it off.
