A fear of mine

I fear that my father will die,
before he knows how truly sorry I am,

for the things I've said to him, and meant it,

he doesn't deserve that, he doesn't deserve that at all,

he does so much for me, yet I'm so f*****g ungrateful,

he deserves Heaven for how much Hell he's put up with,
I wish I could tell him these things in my head, but I fail with vocal words,
