Hello ~ Well, paroxysm means "a sudden attack, or intensification of the symptoms of a disease, usually recurring periodically." So this would mean that you do have paranoia, and the symptoms come on suddenly, every now and then. Does that help?
I hope your therapist can give you a better idea about it, as I may be a bit wrong about it. Hopefully he can clear it up much better than I can.

Don't be afraid to ask him questions -- write down anything you don't understand so when you see him you won't forget what you wanted to ask him. I usually forget everything I wanted to ask. LOL
Best of luck on your visit with your therapist, and keep us posted, ok? God bless and hope we hear more from you. Hugs, Lee
