Not Visible

I don't wear a cast or sit in a wheelchair. I don't have a cane, and I am not deaf or blind. You would never know I live in agony because you cannot SEE the pain.
I cannot be truly honest with people, because if I were, they would certainly not want to be around me for very long. I mean, who would want to hear my tails of woe, loneliness, struggle, and thoughts?
Who would be able to comprehend my deep conversations with God about philosophy and meaning of life, why I'm here, why the world is so dark and evil. Most people don't even see the world that way, and it would be way over their head... they wouldn't be able to relate.
It sucks to be alone in my thoughts, with nobody to really talk to.
