This is it, right?

I have written a letter,
Making of the better,
Not for me,
But for those around me,
I speak truth not lies,
It's okay to cry inside,
I hope for happiness,
In return I am left with emptiness,
I know you have love,
Thinking everything is sent from up above,
It's not okay to be pushed or shoved,
But I remember everything,
Everything always seems to ache my heart with a sting,
But that's life right?
Watching everyone fight,
Preparing ourselves and children for the next,
Always being checked,
Taking pills,
Drinking to get drunk,
Getting cold with chills,
Eventually finding yourself in someones trunk,
That's life right?
Sit back and hold on tight,
It's not over,
Just look over your shoulder,
It's there,
Teaching ourselves and others to share,
I write to show,
It's in paper,
Stop being so down and low,
Just be nice to him or her,
I listen to the stories being told,
Waiting for their book to be sold,
I watch the days that pass,
Knowing our time here is going so fast,
I speak with wisdom,
Knowing I will never wish for my own kingdom,
But that's life right?
