“Hell is empty and all the devils are here.”

Why is sadness just so inevitable? I can be talking to someone, even managing to take my mind off of everything but still, there is no happiness, just sadness. I don’t want to be here anymore. It isn’t even my mum or the voices or ANYTHING; I can cope with that. It is that happiness is impervious to me. Everything could be going fine but it still isn’t worth it. I don’t want to be here, I am tired.
