She has been diagnosed with depression and anxiety, but she also has cognitive decline—where she can’t really do anything on her own—a short attention span, memory loss issues, and will not simply leave me alone. 

For instance, she asks me a question and I say I will do it later because I either want to take a nap or I’m busy. She will literally stand outside my door, which I have to keep locked because she will just barge in, and asks questions for about 20 minutes. She is also incredibly impatient, often asking me to do something instantly, and when I say it can wait she gets irritated. She asks who I’m on the phone with, and other questions, and will literally nag me all day about it. 

I can’t find out what it is, she claims she is perfectly healthy, and her cousin saw recent “improvement” therefore they think she will return back to the normal her.
