I am getting annoyed and don't want to. I have always liked her very very much. But in the last few weeks things have been different. I think she is upset about loosing control, but is not really happy if I talk to other family members or have anything to do with the dog.
Make the bed,, then next day don't make the bed air it out. things like that.
I need to turn this around or leave. Because I want to be good for her.
Fear of losing her independence could certainly alter her mood. Is it possible she MAY be declining a bit cognitively as well? Are her mobility problems permanent or temporary?
It sounds like you would really like to continue caring for her. There are many other professional caregivers on this forum who could probably offer better advice than I can (I care for my mother-in-law), but it would help if you could provide a little more information about your particular situation.
