I have a friend at work for whom i mostly feel affection and respect. We talk about most things and usually I respect her values and life choices. We also have a laugh. However twice she has said that she draws comfort from the fact that my life is worse than hers- in a jokey way, of course. Background: we both live in London, 2 kids and partners and not particularly high paying jobs. In the last year I've also had to face up to the fact that my father has Alzheimers and take on more and more responsibility for him. He lives with my brother who has mental health illness. This has been pretty stressful and i've been helped by attending counselling. Yesterday she asked me what I was doing on my day off. Answer: my father's tax returns. Peels of laughter and the comment about being cheered up by my life being more shit than hers. I'm now feeling I don't want to overlook this. I considered sending her an email about it but think I'd rather say something face to face. I know it's human to draw comfort from downward comparisons when feeling low, but i can say with some authority it's not nice providing the downward comparison. Any advice?
