Cookiemonster, so sorry to hear about your mom. Your mom is lucky to have you.
I know an elderly JW who was disfellowshipped for "wickedness", because she had over a dozen blood transfusions and refused to write a letter stating that it was a moment of weakness, and under similar circumstances she would not take blood again. She hasn't made any attempts to get reinstated, but is still a believer. She was a convert, so her family are not JWs. I hope for her sake they are rebuilding their relationships.
