Maybe if you made more money you could have afforded the treatment to stop you dying...
My last wish would be to live forever. Sorted.
Honestly, I don't think think there'd be much of a point wishing you'd done something on your deathbed. I'd just try and make my peace with what was about to happen.
I don't really know if I would wish for anything, except maybe something simple like having those I care about with me in my final moments? Bring me my plants so I can say goodbye to them, too.
I would just wish for my family to have what they need to be comfortable after my passing. We have a very large amount of life insurance on a 20 year term just in case something like that happens. It’s the ultimate peace of mind.
I wish that my family will receive comfort after I die somehow, and they will carry on with their life, being loving and kind. I also wish that I will see my cats and my family again after I die, which I know I will.
