My mother has struggled with depression for some time since my younger sister died in 2001, and my father, to whom she was married for 53 years, passed away about a year and a half ago. The depression is worsened by chronic pain from arthritis and her unwillingness to take an antidepressant (she says they make her feel "funny"). I live about two hours away, and I call two or three times a week and visit about every two weeks or so. She offers her opinion on what I eat, what I wear, how I cut my hair, my weight, my makeup, my vehicle...the list goes on and on. She's unhappy because I never got married and had kids, so she has no grandchildren. She also complains because I moved away and I'm not there to help her. (She says I do more for other people than I do for her.) She also constantly complains about everything. I know her criticisms don't make any difference to who I am as a person, and I do what I want regardless because I know it's impossible to please her. Sometimes the constant comments wear me down, and I don't know what to say in response. I think I need to do a better job of setting healthy boundaries as far as what she says to me. Any suggestions are appreciated.
