Paranoia can make me very happy. How? Easy. Just someone I trust provokes my paranoia. Since I trust that person, nothing bad can happen. So it is something good. And I become paranoid on every bit of information I get from that moment. The more I get (till not spoiled, of course) — the more I become happy and overwhelmed with what's coming x)
So, to sum this up: paranoia is no bad disease, it's cool and it makes your life richier on feelings =) Don't mind the bad ones, they are neccessary too.
Update: Just forgot to say, what's the best: you guess what it can be, you are sure what it is, and then you find yourself being completely wrong )
Update 2: Awww, fuck my brain, it already sorted it all out =(
