I have ocd and recently I got a fear of schizophrenia. I pay a lot of attention to sounds and ask people around me if they heard it too. The worst thing is that i have a fear that someone may be behind my back. If i focus on it i start to feel weird sensations on my back. I'm afraid that i might actually be schizophrenic and I don't know how to prove to myself if I am or not. Any help?
