Analysis of How it feels to lose a special best friend

The summer we met,
It was one magical,
Through good and bad,
My only friend.

Some time has passed,
We fought before, we played again,
But the nights I couldn't sleep,
You were there forever again.

But the dark day has arrived,
A hurtful one,
An undeserved punishment came,
Who wouldn't even let me say goodbye.

I am still thinking about you,
Feeling like it's my fault,
You disappeared too soon,
I will miss you forever!
