paranoia

Hi.
I am starting to believe that I maybe adhd/add....I have recently started living with my partner who ls adhd. The more I read about it, it feels like I'm reading about myself. But I'm interested to know how paranoia fits into the diagnosis. I have occasional boughts of extreme paranoia....i can be in top form, and suddenly....one word, a look, or even a movement can start me think the worst - that she is having an affair, and it's impossible to shake off...for the record I'm not the jealous type normally....but this paranoia is horrible....
Maybe I'm just bonkers?

Regards.
