I work six days a week and my mom calls me at least 2 times a day asking me if I am done and what we are eating. I have told her that I am busy working and can't talk. She thinks about her stomach every day. I told her to eat something if she is hungry. She is driving me crazy. She gets mad and hangs up. She doesn't seem to understand. She has dementia and is 86.
She is only going to continue to get worse, as her brain is broken, so if you're wanting to continue working, it's best you get things lines up for your mother sooner than later.
