Welcome Debra.
First, while I remember. If this is your real name you might want to change it. This is an anonymous site and we want you to be safe.
Chronic Obstructive Pulmonary Disease
My Mom had this, and unfortunately I do too.
She will do meth every chance she can and loves her beer.
You seem to be in an impossible situation, but still, I think you have options.
By using meth in your home your mother is putting you at risk. First because she is dangerous. Second, it is illegal. And third you could be at risk if something happens to her. I would fear somebody pointing a finger at me.
There are issues of her competency involved. I would keep calling Adult Protective Services to have a record of her mis-behavior and her vulnerability. If she acts in any way as if she is not oriented or delirious, or looks like she is short of breath or has chest pain, I would call 911 and I would have her taken by ambulance to the hospital.
The thing is you have to consent to accept responsibility for somebody who cannot care for herself. I do not see you as more responsible than any of your siblings if you do not choose to be. If you refuse to consent to accept responsibility after she goes to the hospital, I believes that the social workers at the hospital will have to put her in a rehab or in a board and care.
I do not know how you can continue accepting responsibility for her to kill herself. The idea that tenants' rights is the issue here is ludicrous.
I would call legal aid or an attorney if you can afford it or adult protective services so that you can learn your rights.
I am so sorry you find yourself in this horrible situation. There is no reason to continue to be abused.
