My mother has been okay till a year back when I started being her caregiver. But now she has started showing signs of dementia and is becoming more and more difficult to handle. Last week I had bought her a medical emergency pendent but she is not ready to use it and told me that I am considering her old and useless now, and that she doesn't need any help. I understand that people become like this when they are old, but this is really affecting my health. I have this mother on one side and family issues on the other side. I feel all lost and defeated, I don't know what to do.
