She has battled depression for years, and has been treated for it. However,medicines have not always worked. Now, she has mobility issues...can hardly walk, due to several medical conditions. She lies in the bed most of the time - won't even go get her hair fixed. She says she has no where to go and won't be here much longer. Some days, she seems better, but on the days she is really down, I can't reason with her. She tells me to take care of my family (I have 6 year old triplets and am a teacher), and says my dad can do it. She is very critical of him - constant complaining about him - same conversations over and over. He is not perfect, but he is doing what he can. I call her every day, and I see her once or twice a week. She asks me to do things, and I try to, but when I can't do something, she gets mad. She tells me she's not mad, but she goes into the "I won't be here much longer" mode. I am also battling depression, so somedays are pretty bad. What approach should I take with her?
