Paranoia was what tipped my doctor off to the fact that I was bipolar. So, I know what you mean. I have been convinced that everyone is watching and judging me. I didn't really even notice how it started to affect things like how I dress and act. I began to wear dark baggy clothes, not go out unless I was with someone, and tried and be as inconspicuous as possible and blend into the scenery. Once I started to feel better I realized how much I had changed. I seriously thought that the paranoia was normal. My moods are really pretty stable, the anxiety is getting easier to control, but that darned paranoia still hangs on. I keep telling myself that it isn't real, but how do you convince yourself of that when you find out that there are people judging you?
