I have some similar problems… feeling paranoid to the point where it's crippling, whether it's other people talking about me or being communicated with telepathically. Things are a lot worse for me when there is more busyness, talking, multiple conversations, etc. But I've found recently that anti-anxiety meds are helping a lot - I'm just in general a lot calmer. I hope things work out for you and you find a way to feel some relief.
