If I had a "do over' button: I would have done things differently when my mom had Alzheimer's. I would have visited more often, I would have spent much more time with her. I would have quit my job and taken care of her. I would have told her I loved her more often. I would have hugged her. I would have sat with her andheld her hand. I would have tried to show her I loved her more. I have many, many regrets about that time.
