Yes, for certain, you have a plate full of serious issues to address - plus extra family on board to deal with (often a challenge unto itself)!
I’m not suggesting you can magically lead a stress-free life at this moment in time. But the more you can let go of the things you cannot influence and let those issues “be” as they are, and instead concentrate on the short(er) list of issues you can actually influence, the more “in control” you’ll actually be and the less stressed you’ll feel.
Easier said than done? Absolutely. But far better than the alternative approach to life’s challenges.
