How can they explode when asked for help by the caregiver? I'm in my mom and step dad's home helping to care for my mom with dementia. Even with the two of us it is very demanding and getting worse of course. I asked my sister to help out because I need a break and there is no one else to turn to. She exploded and left. She lives 3 hours away and visits for a few hours every couple of months. I'm feeling burned out and desperate. It takes two people to get mom from chair to toilet to bed, etc. I can understand why my sister freaked out, I believe she knows she is wrong. I just can't understand how she can ignore our mom like this?
