i don't know why but the voices are there to haunt me in the night eternally leaving only the thought of regression of self through the creation of fantasy to cope with reality 

These are the questions that keep me up until dawn in my sorrow and emptiness. I cannot escape they say they are there to protect me but in the amidst of the hollow dark i find myself in every time i fall asleep I can feel them creeping through my soul and my veins, i have went to many places for help but it looks like some of them aren't even real places anymore, I don't know if i could continue living this simulation, I can feel the voices of people too they are the ones trying to get me to think that I don't belong in this world.

Do I really don't belong here because of the figment of my imagination, all the faces, all the noise, all the people that I see every day seem to just be something I created off of my loneliness...
I can't do this anymore...
