Hi,

      You are right to keep possitive, most patients need to be encouraged and conforted, and it will help the patients feel strong and want to keep going on their life journey.

      The expereince that I like to share with you, keep talking in possitive way and confort your father, if you still in US, please use skype ( if your folks do have access using it), or phone them.  When you go back, please do the same, it will help the situation.

     Blessing.
