Handling a severe illness is a handful enough, so you do the best you can .
How do you deal with a sever illness? You take into consideration the illness itself .
For instance my grandmother recently died of emphysema . I went everyday to sit by her and help her to be as comfortable as possible.
Sever illness is never easy to deal with. No matter the illness, if it is sever, it is hard to deal with .
Given strength and prayer and your own inner abilities, anyone can deal.
