Those other entities are a symptom of psychosis; they aren't "real" in a concrete sense although I understand they are very real in your way of thinking. I hope you can find a way to communicate to your therapist and your pdoc what is going on in your head and find a way to perhaps take them up on the suggestion that medications could very well improve your quality of life as those entities would have much less control over you and your thinking and you could perhaps make some healthier decisions about coping and living your life. So long as you hide these things and don't get any real treatment for them, they will, unfortunately, probably continue to run your life. At some point perhaps you will see the necessity to be in control and make decisions for yourself instead of letting these not really real entities keep running the show. I hope that for you, but you are going to have to get there on your own when you are ready.
