A part of me has died

I find myself cornered not knowing what is real and what is fantasy. I look and I feel, but is it really real? Did I come across a world of fantasy or did I somehow come across a new reality? Did mankind just create myths from reality to hide the truth? We live in what is called reality, but are truly real? Maybe the human  itself is the myth and other things are the reality. The mind is slowly melting away. We stumble and we fail and we continue the struggle hoping to exist. But what if this existence is nothing but a mere story? What if man really only subconsciously exists? Maybe man is just derived from myths and started to think he exists, but is nothing more than a thought. That was the keen thinking of a great mind.
