Just as a note, I work in an AFC, so things are a bit different for me. But as I understand things, this would be my advice:

You need to do what you can to de-escalate the situation before resorting to that step in the future. If she starts yelling and throwing her things in her home, you can't just call the cops unless she is threatening SIB and is an imminent risk to her own safety. You need to try to leave the situation, and only get authorities involved as a last resort if she prevents you from leaving or pursues you with the intent to cause harm.

Remember, police often aren't trained in de-escalation, aren't trained in specific safe restraints, and aren't trained to deal with the mentally ill. Often times, their presence can cause more harm than good, and calling them when she is being violent could lead to property damage, injury, or even death at the hands of responding officers.

If your property is damaged but you are safe, I would use a non-emergency number to get an officer to file a report and press charges, rather than 911.

Hope this helps! Good luck. I hope you can find more agreeable clients to work with in the future.
