Hollow: The trance

That empty, sad and pessimistic feeling everyone has had in their lives called depression is the experience when we turn our backs to the world and focus on the pain of our soul. This phase could be the sickening of the soul, the stain in our heart, the emptiness of our mind.
But in some cases the mind is the one who imposes this feelings, confusing the heart, disguising the soul. So what is it? Is it really depression or a hallucination?
Is really our soul in pain?
That trance in the reconstructing of our soul, that phase in were we turn our backs to the others trying to question ourselves what is happening to us, is the image I tried to capture.
The reference I took from Google to take this picture is not mine. Nonetheless, the background and the hole is mine
