She is in at least stage 5 of dementia. Every storm we have is the worst one she's ever seen and things might come in the window and hurt us. When there's wind, she's afraid it's going to blow her down. Once she said it might blow the school bus over and half of them would die. When we went to see bison she told people that the farmer said they would kill you. He didn't. Now when it rains she watches the patio and says the water is coming right up to the house and she's afraid it's going to come in. It's nowhere near. The very edge of the patio is all that's wet. I'm sad that she feels afraid and also it's hard for me to hear and try to soothe her. Who decides when she might need some medication, what are options and how do we decide?
