Doubts - PADCC 18

This poem is useless

As is its pen

I hate to say it

Again and again

Though I can't stop

And some say it's not true

I should write for me

But every one is for you

Everyone preaches

The same stupid line:

"Forget your readers

and let yourself shine."

If nobody sees it,

Then what is it for?

What is the point?

Should I try anymore?

I want so badly

Just to be heard

But nobody reads—

Not a one of my words

Day 18 Prompt: good for nothing

doubts are the worst and make for bad pieces, at least for me
