Invincible or Invisible?

Am i invincible or invisible?
I feel no pain yet there is pain
I don't feel depression yet there is depression
I don't feel sadness yet there is sadness
I am not lonley yet there is lonliness

But then again...

I feel pain when there is no pain to feel
I feel depression when there is nothing to be depressed about
I feel saddness when there is no reason to be sad
I feel lonely when there is no lonely

So... am i invincible or invisible?
