Hello Strugglingwith life, and yes, you are so right.......life is indeed very cruel at times. and it seems to be that it is always the nicest people that suffer the most.  The best thing that you can do for your Dad is to simply be there for him.  If he wants to talk about what is happening to him, then allow him to talk about it.  It will be very hard for you because it means that you must hide your true feelings in order to be strong for him.  That is not an easy thing to do.  Also, please tell him how much you Love him.  I nursed my Mum through cancer and one of my biggest regrets is that I never told her how much I Love her.  We did not have an easy relationship......in fact, there were times when we drove each other crazy, but how I wish I had told her that in spite of everything, I loved her very much.  Tell your Dad what a wonderful Father he has been, and that you have so many wonderful memories of the good times that you shared.  I suppose that what I am saying is that you must not leave anything un-said.  When the inevitable happens and your Dad leaves this world, it will give you a lot of comfort to know that he KNEW how much you Loved and cherished him.  Yes, you will still be devastated, but at least you will find comfort in the knowledge that he knew how deeply you Loved him.  Take care my Love, and I am so sorry that you and your dear Dad are going through this.  Life is indeed very cruel. xx
