My mom has a lot of health issues, depression being one of them, but it's getting almost unbearable, at times. She is mad at my dad over an incident that happened a few weeks ago and won't let it drop...she fusses about him, she fusses about me to me, she complains about all her health problems (she does have a lot), she complains about everything in her life, it seems. She is 81 and still seems to be thinking clearly, but she has gotten so negative in the last 2-3 years. There are no solutions to her problems, according to her, when I try to think of some. Nothing will work - she's tried that and she knows it won't work. I am about crazy from listening to her fuss for 30 minutes or more at a time. I am an only child, so I am the one who hears everything. I am also raising my own family, have a difficult husband, and a demanding job. I do call my mom every day, but she is dragging me down, emotionally, and I don't need this right now. She is on antidepressants, but they don't really help - have been changed many times. I think she needs to see a therapist/counselor, but she says she's done it before and it didn't help. What should I do, and how should I handle this?
