Bipolar Me

As i feel the small pricks from the gravel on my bare feet
To my amusement there is no pain.
As every piece of glass slices through my skin
I laugh as I think of the blame.
I'm back to feeling like a nothing
I have no ambition
And feel all the shame.
Who am I ?
Where do I go ?
How do I continue play this game.
Bipolar me
A new me everyday
But never the same.
