Hello, Damon. His friends here may appreciate any memories you wish to write about your dad. In any case, please know you are not alone in your grief. Find someone to tell about your happy memories, your sorrows, regrets...stories about you and your dad.

Express your love for your dad in some way. He sounds like a gentle man from many of the comments here- likely he'd not want you to torture yourself.

Best wishes,

Maeve
