I would not film her because in some states, that may be unlawful. She could sue you and that may take years to settle even if you won. Then I also think you have to be careful with what you say and do with the landlord. Again you might cross the line even if the landlord agrees, and that could bring on another attorney/attorneys. What the landlord does, because you made such a report to him, might be something you regret. I agree she is in bad need of a psychologist, or even better, a psychiatrist, but I would fear asking her what she thinks would be best. You may need legal advice, or maybe there is someone in the field who would be willing to come talk to her. But then again she may have great anger towards you if she knew you set it up. You may not be able to get out of your lease, unless the landlord releases you, but then his next renter has to deal with her as well.
