COUNTDOWN

it’s going to be a year since my Dad died in less than a month…
i’m on some kind of sick countdown…why do we do this?

why do we put such significance on how long since our loved ones passed? and what does it matter if it’s a year, a month, a week or 15 days…?

what purpose does it serve us apart from dread and anxiety…and it’s so morbid when we mark the very date/time/place that they died?

can someone please explain to me this phenomenon?
