Losses

My mother had dementia before she died. She was blind most of her life. When she began to lose her memories, my heart broke for her. She became a person trapped in her own body with no colors or lights and little knowledge of who she is or was.
It was a hard road for her. When she finally succumbed at the end, part of me was relieved that she was free and maybe in a better place with my father and brother.

Was it wrong for me to feel a little relief that she was finally set free?  Is she in a better place?
