Mother has been obsessing over everything. I know her world has gotten smaller and she is afraid. This week she started having nose bleeds and the caregiver said she may have scratched the inside of her nose with her nails. Today I saw that mother had tweezers and I asked her what they were for. She said that she plucks her nose hairs with them. Maybe that is why she has nose bleeds. She was very angry with me for asking her questions about what she does. She feels that no one lets her do what she wants. I say we are trying to keep her safe. She does not understand any explanation because she is very hard of hearing and has dementia. I have asked the caregiver to hide the tweezers. Trying to discourage her behavior may be a lost cause because of her condition. A few weeks ago her obsession was shaving her legs with a razor. It seems when we take one thing away she finds something else to obsess over. I am at a loss of what to do because she gets upset very easily. Any advice would be appreciated.
