Yep. In the advancing stages of Alzheimers, those who have the disease cannot feed, drive, clothe, or bathe themselves, they become dependant upon others to do menial tasks such as brushing their teeth, coordinating their outfits, running errands, they even reach the point that they can get lost in their own home, or think the caretaker is someone who broke into their home and lash out at the caretaker. For a caretaker, they're doing the job of two people, the one they're caring for, and running their own personal life. Caretaking can become so stressful. It's been a two year "learning experience" for me as a caretaker to my grandmother.
I commend you for taking care of your grandmother. I took care of my great grandmother from 95 to 98. She fell and broke both hips in 98 and spent one year in nursing home before she passed on.
Not many grandchildren are going to take care of their grandparents nor do many now.
My gram lived longer then 2 of her 3 children and her surviving son lived in another state and we felt it best to keep her with me. Also I knew she preferred to be with me because she never had a good relationship with her daughter in law.
After she went to home I suffered through depression because I could not believe I didnt have to worry about her anymore. Her passing while sad was not tragic. I knew her heart would stop beating someday as will all of ours.
May God bless you a thousand times over for what you are doing for your grandmother. I salute you and all other caretakers. It is a unique bittersweet hell in the end days.
