I Hear Voices

I'm not sure I would call them that. most days it's an unknown voice that tries to disguise itself as my inner thoughts.. but all of what it says is usually not my thoughts. The fact I'm alone alot makes it more disturbing for me.. I try to always answer it back and it seems it has made itself comfortable in my head.. it goes over everything I've ever done in my life..and always tells me I did it wrong or the bad parts were my fault..I am already somewhat of a low esteem person.. but I can relax and let things go..not anymore, ever since this voice came to stay ..I've been in and out of reality quite frequently ..I'm just not sure of what the illness is, but it whispers on my emotions and on what's going on..I have no idea where the real me is anymore..or what a real thought is..I can't have one.
