My coworker is a lady in her early 60's and she and her brother and sister are looking after their mum who is 92 with dementia. Every day she will come into our office to fill her kettle (as her office doesn't have a sink) and she will give us the latest on her mother's mental state; even down to her bowel movements and what her mum leaves hanging around her flat in strange places. She updates us daily about her mum, so much so I feel drained after. It's not like she's on her own to look after her mum, she has a huge family. When it's just me in the office when coworkers are off, she'll go on sometimes half an hour telling me about her mum.
Anyway, this morning, she came in to fill her kettle again and my coworker asked her how she was and she said, "Oh well. You know I was thinking about my mum and the winter and how if it snows how will her carers get there on time". I said to her, "Well, let's hope the snow won't happen. We have to think positive" and she bit back, "BUT I CAN'T THINK LIKE THAT, THAT IT WON'T HAPPEN BECAUSE IT MIGHT". It doesn't matter what I say to try to say to pacify her in the past as well, she comes back with some slight attack. How should I handle her when she comes into the office in the mornings? I'm starting to dread her visits. I can completely understand her predicament, but she doesn't even ask how I am!
