Yvonne - you and your husband need to know you could be in for some seriously turbulent times. I wish you all the very, very best. Through it all, keep yourselves grounded and just be thankful you got your parents out of there. Thank you for the information. Again, I hope you are able to get Jill the help she needs. It’s a long road in helping people like this, they tend to be very resistant, sometimes emotionally aggressive, sometimes even physically aggressive, when their hoarding and other issues are starting to be addressed. Get help with professionals as there are many programs of assistance. The first step could be discussing things with your physician to get things going medically. The other is social services, City or County services and also animal assistance services. You have an ENORMOUS task on your shoulders and I send my prayers your way. Keep your chin up and stay strong to each other.
Start by having a family meeting and discuss as a family where your action needs to go, and together as a family, how much action to take.
From there, you can enlist the help of medical services and police services to carry out the medical services plan.
I work in medicine. Here in Alberta, the Mental Services Act allows for serious mental illness patients to be detained on a Form 10 so they can be restrained and brought to medical attention at the ER - The Form 10 is usually engaged by the Police who provide transport. From there, the ER physician assesses them and may begin proceedings for a Form 1. A further Form is filled out once Psychiatric services have been called in for further assessment and the Psychiatrist decides whether the patient is at risk of harm to self or others, or mentally deranged (whether temporarily or permanently) enough to not be capable of making decisions for themselves. Two psychiatrists are needed to sign off on a Detainment Form so that the patient cannot legally leave psychiatric treatment - they essentially become an involuntary patient. If the psychiatrists do not think things are serious enough for detainment, the patient can be kept as a voluntary patient (meaning they can leave if they want) especially if the psychiatrists are able to convince the patient they should make the right decision and “volunteer” to stay to get treatment.
This is a place to start with your medical doctor and he/she can start the ball rolling as according to the Mental Health Act in California which probably has slightly different terminology than up here in Alberta. I just gave you this information to help you have a place to start, should your family decide to engage in this.
