I have attacks of paranoia, too, and in my delusions I think I can hear heavy boots tramping on the stairs up to my apartment, as a police SWAT team moves into position to take me out. This has happened only a few times, but I share with you the paranoia that corrupt cops are setting up false evidence to send me to prison. Or that the cops are going to shoot my friends, etc. All this becomes quite stressful sometimes.

In your case, it sounds like you need to try some medication, or CBT (cognitive behavioral training) techniques. It can't hurt to try, and they might help reduce your symptoms or get rid of them entirely. Worst thing you can do is just holding the course, because obviously the situation isn't getting better on its own...
