Sorry, to hear,
My mothers been on dialysis for about a month,
It sucks!!!
Just gotta find your way through it.
As for staying out doors, dialysis shouldn't stop you,
Will change your routine though,
Can't take long hikes where you need fluids,
Remember your 1ltr max daily fluid intake,
And there are groups that can help
Look up owl outdoors without limits. See if they have a chapter near you
