These walls

I cry and I cry,
But no one seems to hear me.
Why cant anyone hear me?
Is it this bubble ive got around me?
Or is it because im paying to much attention to my scars?
Or maybe its even these walls ive got up around me?
But i thought they were to protect me from my insecurities?
I want someone to hear me, help me, protect me.....
But no one can hear me.
Its these walls ive got....
What have i done wrong?
I thought it was best to have them?
