Advice on what to do next?

I am a single child that lives approximately 200 mile from my mom. She has dementia. Her short term memory is not good but she can function some on her own. This started after around Thanksgiving last year after she fell at my house. We had her admitted into a psych hospital for 2 weeks and then she moved into a very nice assisted living place. She was awful there to the staff and constantly complained to me until we moved her out.

She then moved in with us for about 3 weeks. She also stayed at our condo in our town for about a month after that with caregivers. She constantly complained about how miserable she was and eventually had a friend drive up in the middle of the night to take her to her house.

She stayed at her house for the summer with caregivers coming for 4 hours a day. I wanted longer but this was they only thing she would tolerate. Last week she fell in the bathtub and couldn't get out. I placed her in assisted living on Wednesday. Sunday she got a ride from a stranger and went back home. Her cell phone wouldn't work so she called 911 and had the police come.

Today she had turned her AC so low at the assisted living place that it froze up. She called 911 and told them she was being traumatized. The cops came. I just spoke to the manager at the assisted living and she asked what I was going to do with my mom? She said that my mom acts like she is having panic attacks and always want to be on the go. Which is true. She always has to be on the go. Always.

I am at a point where I don't know what to do or where to go. I have a very understanding wife and kids age 14 and 12. I can't hop in the car 3 or 4 days a week to go babysit her. Feeling helpless!
