Listen hard and there will be one inside your head that tells you to get yourself to a GP. He/she will be able to help you very quickly. There is nothing anyone can do here for you to make it better.

those are demonic spirits. you need to talk to God, he's your only protection from them. and please take heed to this, the enemy works because he wants you to believe he's not there, when he is. i'm not shoving my belief down your throat as those people stereotype it as, but i'm only offering you and answer you asked for.
Talk to your doctor he can give you meds to help stop the voices
Take your meds. Call your doctor. Go to the hospital.
