Well anxiety will certainly have something to do with it. Sounds as though you may be getting yourself so worked up that the problem has ended up being worse than it started out.

If you are in fact having paranoia and delusions you need to find someone to help you - your doctor, your psychiatrist, the emergency room are all a start. I can understand being hesitant to do so but these people (should) treat you compassionately. What it really comes down to it is do you want to try and ignore the situation or help yourself.

You have not given us much detail - which is great if you don't want to. It is difficult though to judge the extent of what is troubling you. Regardless though of how extreme these thoughts are that concern you I still encourage you to talk to one of the above to sort it out.
