Very sincere condolences on your loss.
Here are sentiments from another daughter who also lost her dad to prostate cancer. I hope the feelings expressed may be of some comfort to you:
My Dad My Angel
by Jamie Cirello
Your battle is now over, no more tears flowing down your cheek,
no more pain, no more suffering, now you are no longer weak.
I still do not understand why this had to happen to you,
but I am proud to say you are my dad, the greatest man I ever knew.
Although you will not be here to walk me down the aisle,
when that day comes I know you will be by my side with a smile.
You were always there for me and never once made me cry,
until the day you closed your eyes and had to say goodbye.
Now you are my Angel, so spread your wings out wide,
please wrap them around me whenever you see me cry.
Our time together was memorable and God took you way too fast,
But the most precious thing to me was you being there for my first breath,
and me being there for your last.
