Mom is upset because she thinks that she is becoming a burden to me. I feel so awful for her, that she has to go through this. I hope I am not making her feel burdensome. Her happiness and comfort are very important to me. Her moods seem so changeable. One minute she is laughing and the next she is teary and crying. I think it's the dementia, but we can't just mark everything up to the dementia. We have to make sure there are no other reasons. That's why I'm taking her to the doctor, so that the doctor can observe her.
