Her doctor is aware and wants to switch meds. She is paranoid about everything. Not sure she will do it. My sister and a couple of other family members are aware, but I am living with her. The last blow up was brutal. Have you ever called 911? Did it help?
If that is the case, then you may need to call EMS for trip to ER. At point of intake tell them you require social services help for placement as you cannot physically or mentally take your Mom back into your home. Do not argue. Do not swerve from that basic statement. Do not believe them when they deliver the platitudes of "We can work together and get you help" or "We can make this work". They cannot and they will not.
It is up to you how long you can sacrifice your entire life to this reality. I am so sorry, but that is the brutal fact. There is no fix it for many situations, and this is one for certain. I am assuming this deterioration is ongoing over time, not sudden as it can be in the case of a UTI. I am so sorry. I so wish you the best.
