To the one who left---

This is to the one who left-
you absolutely do not know what you've done.
You've crushed me, absolutely crushed me.
It's everyday, I see you everyday, in everything I do.
And I don't know what to do.

You see, I can't figure out if it's you, or the reason why you left.
I mean, many times in my life I've left for the same reason, I've left people's lives because I'm sick.
Just like you left because I'm sick.
But that doesn't solve anything. You just ran away from the problem. And created another one.
You broke my heart. And I can't function without you anymore.
