I completely agree with everything Pam said and I do understand exactly what you are talking about.
My Dad (Vascular Dementia) and my Mom (Alzheimer) both have dementia. Dad is relatively happy but Mom mom is fighting against this disease with all that is within her. I have written extensively about her fear, anger, rants, tear, and angst. She wants to go home. Her world has gone crazy. She truly believes, if we just let her go home, then the chaos in her head will go away and all will be well. She will pleed, beg, threaten, get angry, and disowns us regularly. We are in a conspiracy to make her miserable. Yes, it is all hard to hear but in my heart it just validates that she is where she needs to be. I want my Mom to be happy.... but my first responsibility is be sure that my parents are safe and well cared for so I have no regrets.
I think this is one of the hardest parts of this disease.... or it has been for me. Then one day I realized that Mom's desire to go home was not to go back to the house where she lived with this debilitating condition. It was a cry to go back in time when she and Dad were healthy and could live at home. I know in my heart that it is impossible. This disease does not get better. As I said before my first responsibility is to be sure that my parents are safe and well cared for... and that is what we have done
I do hope your Mom adjust to her new surroundings and life becomes better in that way.... for both of you. I will keep you both in my thoughts and prayers.
