Wow. This person is a psychiatrist, and probably/possibly bipolar and alcoholic.

I've had neighbor problems before, but I sure don't envy you. No matter what her problems are, she is still responsible for her actions.

You've elevated this to the level of the court. Though the legal route is slow and has its limitations, I personally feel you've done the right thing.

Now is the time to DOCUMENT, DOCUMENT, DOCUMENT. Photograph/video the after-effects of her actions (for example, the debris in your off-street parking area) - or catch her in the act (as long as she is on your property or in a public space). Log time, date, place, witnesses. Find out all you can about her through public sources. Get a discreet recording device and keep it on you if you confront her out in a public space; let her talk, rant, etc.

Serious question: is she armed? Does she possess a weapon of any type?

If you have to approach the police, have evidence in hand. Document your meeting with the police. You were calling a neighbor to witness - great! Enlist the support of friends and neighbors. Chances are you are not the only one troubled by this person.

All of this may be beyond your present capacities or be too triggering. Inform your caretakers. Lean on your friends and neighbors. Handled correctly, this "fight" could end up benefiting everyone involved - including your neighbor and her patients.
