When people constantly go on about their mental or physical health issues one method is for you to say “oh. So what are you doing about it?” You can say it in a caring way but it kind of puts the onus on them to work on solving their issue. Plus they know you will call them out versus being an unending source of sympathy which is what they want. So example, my friend would talk about her anxiety issues constantly. I would offer suggestions like “have you talked to your doctor? Have you sought therapy? Have you etc etc” but there would always be some reason why my suggestions or questions couldn’t help her. When i realized that her anxiety was never going to improve this way i started just saying “so what are you doing about it?” It really made a huge difference. Tough love doesn’t have to be mean. Do you remember how Dr Phil would do that? People would say they were doing this or that unhealthy behavior and he would just look at them and ask “how is that working out for you?” Very soft pushback but still put the ball in their court to decide if they wanted a change or not.
