What is the name given to a poem of fifteen lines?

A Life of a Life

My friends left me, they always leave me.

Nobody wants to be with me.

I feel like I'm invisible.

And I feel that all adults, kids,

and every living creature thinks that the

world would be better without me.

I know my parents regret having me.

But soon enough, it will all be over.

I just wish that someone, somewhere will

care about me because they want to, not

because they have to.

I try to fit in, but I feel people think

that I am a poser. I guess you can call

it "posing" or "just trying to fit in",

but I call it "trying to not be alone."
