Sounds like a horrible, soulless woman. I think as she is sarcastic and mean, she will see through any act of kindness from you as disingenuous, even though you will be very gracious. Not standing up to a bully (which some people have suggested) would let her think that this way of life for her is acceptable. Illness is not an excuse to berate or constantly put someone down. She is mean and needs to be dealt with. I despise nasty people - see, it has the negative affect of making one have negatively in one's life for others, when they are negative toward you. This woman's business is not in the Church, not in any church I know. How the others let her carry on I don't know! - they need to self-assess. She needs to have her bad manners and nastiness nipped in the bud, or she wont get into heaven - that is, according to the rule book!
