I feel that I am on the verge of a nervous breakdown and then I won't be any good to mom or anyone else.

Mom is 84, dad is 91 and dad has alzheimer's, mom is showing signs of dementia, I am the daughter and caregiver. mom has home care for pills Mom is afraid that someone is casing her home to break in and hurt her. She called the police because I did not show up at 5 and thought something happened to me. The police were waiting for me to arrive and asked me if she is a little confused. I have had to stay at her house so that she can sleep for fear that something could happen during the night. I am burnt out. My brother and I have found a retirement residence for her and we can move her anytime, but how do we do it. We require mom to write a cheque for $500 to cover the damage deposit and sign the paperwork as we do not have guardianship. She said she needs a couple of years to make the decision to move??? She lives alone in the house. We have turned off the gas stove because she left it on and gas filled the house. She was not taking her medication so I arranged for home care to come in to assist me. I see her wearing the same clothes all the time although she is clean, she is very forgetful. My brother and I are just looking at how to actually move her. I am worried about myself as I feel that I am on the verge of a nervous breakdown and then I won't be any good to her or anyone else.
