If her problem is alcohol or drug related, it may take getting reported for her to get help.

I am an addict, myself. I have seen, so many times, addicts and alcoholics come in and want to stop, know they need to stop, but they can't. They keep having consequences, small or large, but nothing helps. Until the one thing they value most is threatened, they will not be able to fully understand the severity of the situation.

For me, that one thing is my life. Drinking and using makes me extremely depressed and suicidal. Almost every attempt I have made on my life, I was intoxicated. I had to understand that the drugs and alcohol were going to kill me, one way or another.

For her, if that is what is going on, her career being threatened may be what it takes for her to ask for help. I'm not saying actually report her, but reminding her of the ethical responsibilities you have could be enough for her to talk to you, and then to someone who could help her.

You are her client, not her T. I can tell you have a very caring, empathetic personality. You want to take care of her. But you are her client. That is not your job.
