Analysis of A Different Way (MAJOR TW for self-injury)

I brace myself
For the oncoming pain.
I hear the many rips
Of my hair yanking out,
One by one.
I stare for a moment
At the bunch of hair
In my hand,
My eyes watering from
The expected pain.
I feel the throbbing
Of my head,
Deprived of some hair.
My head now aches
And throbs;
The top of my head is now
Raw from the forceful yanking.
I hide my now-detached hair
In a clump of tissues,
Hoping no one will notice
So I can dispose
Of the evidence,
So no one would know
That I have
Ripped out my hair.
