We live together. My mother is always talking to me in a demeaning manner. We get along sometimes however she seems to always nag at me and say things that I "used" to do when I was drinking. I try my best to be there for her and help her around the house as she is in her mid 80's but my best seems to never be enough. She was never really a caring warm mother while I was growing up but once my father passed it seems as though she has it out for me. I'm the only one there with her. Sometimes she says such hurtful things that I sometimes come close to taking a drink! I am at my wits end...Can someone please give me some advise?
