My Own Worst Enemy

Help! I'm trapped,
Being chased around.
Someone wants to hurt me,
Bury me in the ground.
I'm running for my life,
Crying as I pant.
Time is running out,
I can't be caught, I just can't.
Passing curves,
Sharp twigs and snakes near.
It's coming closer to my face,
My whole body shakes with fear.
I'm wondering, thinking,
Who could this be?
I pull of its mask-
To my shock, it's me!
