Your writing style and the way your describe what you are experiencing reminds me so much of another poster, Eden. She also thought she was experiencing demons and had a lot of paranoia. I think she was able to get some help and those symptoms improved for a time. Hopefully, you will be able to talk to your doctors and get similar help so that you are not so scared and sad. It might be time to consider the hospital to stabilize your symptoms. Call your doctors and let them know what is going on; you don't to live in this state of anxiety. I hope things improve for you.
