A cabin in the wilderness

My aunt Mildred, who lives near the wilderness, has dementia, wanting peace, quiet and to be in control of her own life. She is having hallucinations now and some memory problems. She has spent most of her life taking care of my grandparents, who were abusive and controlling. She doesn't see it that way though... She has never complained. Now she just enjoys the peace of the mountains and sweetness of each wildflower. A hard winter is coming. We have tried to prepare with wood and food and supplies. But we are worried. Will she remember where she is?  Get lost  thinking she is taking a walk where she lived as a child?  In better days she was clear she wanted to "live and die" on the mountain. It was easy to agree then. Now we are not sure. Loving her is so easy... Making decisions for her well being is beyond difficult. But every day I thank God She is in my life.
