My 65 yr old MIL lives with us, and she has been in depression for 7 years ever since being diagnosed for stage 1 cancer. At the same time, my FIL had Alzheimer's and deteriorated overtime. Both have lived with us for the past 11 years. Her depression has worsened ever since we moved my FIL into a memory care unit 3 months ago. She cries, worries about her husband, and says she does not know what to do with her life.
My wife & I are very frustrated. Even our 3 young kids don't really want to be with her. She has always been overly dependent, slow to adapt (if at all), and stuck in her ways. Depression makes it all worse of course. We've recently changed her medication without significant improvement.
I am not optimistic, but she is family and we are not ready to give up just yet.
What I want to know is, what are the possible outcomes for somebody like her? If she will remain this way long term, then I must protect my wife/kids from further stress and move her out. People might view this as abandonment, but I will do what is necessary to protect my family. Living with them all these years were tough and a big mistake.
