I am sad to hear this news about your father. As a husband and a parent I worry the most about my bride and my children being in a good. If you can let your dad know that you will be ok because of the fine job he did raising you. It will comfort him and give his soul peace. This poem was written by a man that had lost his wife and two daughters. Yet he did not lose hope. Sometimes it is very difficult to stay hopeful. Especially when life is not fair. I hope the poem will bring you some comfort 
  The First Snow-Fall By James Russell Lowell
 
 
THE SNOW had begun in the gloaming,   
  And busily all the night   
Had been heaping field and highway   
  With a silence deep and white.   
 
Every pine and fir and hemlock          Wore ermine too dear for an earl,   
And the poorest twig on the elm-tree   
  Was ridged inch deep with pearl.   
 
From sheds new-roofed with Carrara   
  Came Chanticleer’s muffled crow,          The stiff rails softened to swan’s-down,   
  And still fluttered down the snow.   
 
I stood and watched by the window   
  The noiseless work of the sky,   
And the sudden flurries of snow-birds,          Like brown leaves whirling by.   
 
I thought of a mound in sweet Auburn   
  Where a little headstone stood;   
How the flakes were folding it gently,   
  As did robins the babes in the wood.           
 
Up spoke our own little Mabel,   
  Saying, “Father, who makes it snow?”And I told of the good All-father   
  Who cares for us here below.   
 Again I looked at the snow-fall,           
And thought of the leaden sky   
That arched o’er our first great sorrow,   
When that mound was heaped so high.   
 
I remembered the gradual patience   
  That fell from that cloud like snow,          Flake by flake, healing and hiding   
  The scar that renewed our woe.   
 
And again to the child I whispered,   
  “The snow that husheth all,   
Darling, the merciful Father           
  Alone can make it fall!”   
 
Then, with eyes that saw not, I kissed her;   
And she, kissing back, could not know   
That my kiss was given to her sister,   
  Folded close under deepening snow.
