My mother behaves as if she's helpless whenever she is with my sister and I. Cant stay awake, slurs her words, can hardly walk, forgetful and complains constantly. She then receives a phone call from her girlfriend and low and behold she no longer is slurring her words, she is happy, laughing, and planning her next music outing. Even tells her she is having a great time with her daughters. We were on a 4 day camping trip which she did not participate in anything, only came out of RV to eat twice Yes my mother still drives, attends music events were she sings and plays guitar, and has a social life. If we make a comment about her complaints and unwillingness to do anything for herself she becomes defensive and angry. Mind you I spend a lot of time with my mom without my sister as I live around the corner from her, and she does not behave this way when her and I are together. This is a new situation for us and unsure how to respond to this behavior, She does have a treated mental illness. I am so upset with her acting this way that I'm having a hard time being around her but can't leave this all on my sister.....HELP.... I posted this in the wrong place the 1st time. New to this forum and posted under someone else's question, all feedback appreciated.
