I know how you feel I lost my granddad (my dads side) in 2014 and it was a big lost in my family including for my nan I still his cap he gave me when I was small. So your not alone man
Today would've been my grandpa's (from my dad's side) 92nd birthday. Both my dad's parents died when I was really little and I barely remember him. I miss you Grandpa, wherever you are.
