This was written by a friend of mine after he lost his son:

Grieving

I had some time to prepare
For the loss
But it didn’t matter —
It hit me like a ton of bricks
Not immediately
It waited
Until I thought I was managing
Deep sorrow set in
Permeating the air
Thick and heavy
Making it hard to breathe
Then later into longing
To have him near
Tugging at the heart
Not constant, but intense
When a memory would trigger
Flashbacks, real or hoped for
The could-have-beens hurt the most
As the mind plays tricks
Savoring memories never realized
I was told that Wounds would heal over time
And be replaced by sweet emotions
Maybe soon
For now the longing
Waits outside the door
For my mind to open
Letting the feelings flood in
And tear at my heart.
