Adult diapers at work

No, i don't wear diapers at work but there is something about adult diapers that is keeping me from staying focused on the job. i work for an ad agency and for almost 3 years, i handle an account which is a brand of adult diapers. all those years, i still haven't got the hang of it. I'm doing a bit better now, but i still catch myself tearing somehow.
My beloved grandmother met a freak accident back in 2002, she was fine, healthy and active until she bumped into a glass door and fell backward, landing on her buttocks. She was confined to her bed, still the same grandma i know, only this time, she wasn't in the garden looking out at the sun and keeping it neat.
It was sad seeing her eat, bathe and piss in the same place, never seeing the sunlight as she sat in the garden she watered everyday. Almost a month in bed, she was making progress, we can tell she was already healing but the worst can happen.
She was an active person suddenly confined in bed...cardiac arrest was never far and it got her.
I was on my thesis and was out doing research until late, mobile phones did not have the battery life it has today and it didn't really matter.
I went home and found my sister by the garage, tears flowing, it was unusually quiet. I was dumbfounded--i didn't see it coming. For a moment there, i lost my mind and broke down.
I went inside the house and met the arms of my uncle, i went inside the room and looked to my left where the storage room is, what do i find? Packs and packs of adult diapers that didn't even get to do their purpose.
Everytime i look at the materials I have to work on or formulate PR plans or write articles on it, i submit myself to breaking down. It was a vivid memory of one of the saddest nights of my life.
It always hurts to look back on a sad past to communicate relevance in the present but that's what being a  self-proclaimed writer has to live and deal with.
