Quote from : Killing Lions: A Guide Through the Trials Young Men Face Book

Sartre felt that Hell is other people, but precisely the opposite is true. Hell is being left alone forever with no other reality than your own consciousness of yourself. It is being locked in a casket of your own internal chaos with no hope of a window, or door leading in light from outside to give you a moment's respite from yourself. Hell is the refusal of the gift of the other.
