She came to live with us 9 mo ago when fil passed. She has dementia and other issues, so she can't live on her own. I have always clashed with her, but we somehow kept the peace over the last 33 years. She seemed to change while her dementia got worse over last 3 years, and we got along fine while I took care of them when they still lived at home. Now, I'm seeing the traits and behavior from the past, and it's ringing old bells. I tell myself she is sick and doesn't know better, but in the end I still react, then get upset with my behavior. I used to be a compassionate person.
