I have Bipolar with Psychotic Features (and for me that's paranoia). I've suffered with it for years. Risperdal helps me a lot.

Paranoia is a delusion not based on fact. I have to use the ABC format of Rational Emotive Therapy to help me distinguish between fact and fantasy.

A. Activating Event (Write what the triggering situation was)

B. Thoughts/Beliefs (What am I telling myself about the event)

C. Feelings (How does it make me feel)

D. Dispute any Irrational Thoughts & Beliefs

Sometimes when I see it written down it helps me to figure things out.

I wish you the very best.
