i’m terrified my dad is going to die

i called my dad the other week while i was packing my stuff up to love out of my dorm and move in w him for the rest of the semester and he was making his living will (he said because his lawyer wanted him too; idk though bc he included my grandma in it and that’s part of what scares me as not to be morbid and i love her god forbid but shes in her 80s)

but i’m really afraid he’s dying or sick and isn’t telling me. he’s been having problems with his knee for a couple months and he’s taking prostate supplements (i didn’t look for them!! they were on a counter in the only bathroom there is in the house) and idk i’m just terrified of losing him
