Analysis of Is grief a god?

This is the human heart, A heart that feels loneliness, A heart that feels heaviness and emptiness, and true love.
Death marks the end of one chapter ‘Cause the soul lives on, eternal and free
Though my breath may cease to exist And the world I know comes to an end, My heart will always be with you.

Crises don’t kick a swing one might miss, Everyone around me was already working on plan A,B,G and going all the way down to Z
All I’m doing is memorize the details of your face Like it’s the first time I’m seeing it or maybe it’s the last.

This is the human heart, It’s a heart that’s able to feel loneliness
This is the human heart, it’s a heart that feels happiness and pain And true love.

You made me believe I was all you needed Yet you left without a warning and that made me feel really worthless
You were so far away when I cried out your name You heard but the echo wasn’t mine

I made myself hate you ‘Cause it was easier than missing you
Everybody wants a happy ending but it doesn’t always roll that way

It’s sad I always find myself clinching onto people that aren’t meant to stay
Bad things happen to everyone But I suck at dealing with it
For me it’s easier to be sad than angry And as time passes by, I forget there’s a difference
