I was experiencing for a few months intrusive thoughts, voices, thought broadcasting and paranoia that i'm being watched and listened at home, in my car, outside. 
Now i don't believe that voices are real anymore and their presence diminished by over 95%, but i still struggle with paranoia. It's enough to see a stranger sad or angry on the street and paranoia makes me feel like they are angry at me. If there is some peculiar coincidence related to my life on tv, radio, when socializing, my paranoia instantly adds the coincidence to the collection of disturbing nonsense and then i have to rationalize over and over again that it's all nonsense. 
How do you deal with your paranoia?
