I can sympathize: my mother is nearly ninety and has been really
horrible for the last three years. My sister has been wonderful because
I haven't been well. I was the good daughter for thirty years and now
she is, and we both are united in dealing with our Mum. For yoursdelf,
you have to learn to turn off and just agree with everything they say
and do your own thing.. good luck again as it is ongoing unfortunately,
which is why you need to learn to keep yourself gpoing and not deal
with them at your own expense.
