Analysis of Fast

I sit and think,
About my past,
Of running hard,
And living fast,
Of who I was,
Not long ago,
Of giving up,
And letting go,
All these thoughts,
Run through my head,
Sometimes I wish,
That I was dead ,
Will they cry,
Or even care,
My mind is heavy,
So much to bear,
So I'll just sit,
And shut it out,
No one will notice,
Without a doubt,
That one day,
I just disappeared,
My voice is something,
They no longer hear,
I'm fine with that,
Soon they'll see,
I'll be okay,
Not being me.
