i have become comfortably numb

"now sadness sickens my hear and confusion blinds my sight
alone I feel so alone
maybe I’ll turn this feeling into a wall of stone
and build it big and strong
I’ll build it around my heart and let no one but you tear it apart
so here’s your invitation
I hope you will accept
remember the days in the sun and promises kept
I’m writing these worlds from behind this wall"
