Who can change the future?

Who could erase the chalkboard?
Who could even dare to defy the past?

I may act strong,
However on the inside,
I am but the weakest of wimps.

There are my walls also,
A mighty fortress they seem-
Instead merely a paper model.

I could drone on about how

I'm just another depressed teenager.

But there isn't a single soul who would believe me.

Because that's what I do.
I put on a mask and wear it.
Until I realize it could never last.

All the lies.
All the secrets.
All the charades.

That's when I begin again,
Erasing all of my old friends.
Erase even the hint of a memory.

But who am I kidding?
After years of doing this,
It keeps getting harder to begin again.

After doing this for so long,
I keep wondering,
Who I even am?
