Some of these factors you listed are sometimes promoted throughout the media as "hot button topics". Depending on how informed we are, these news stories could very well manifest themselves into paranoia throughout our everyday lives.

I'm not suggesting watching or reading news stories caused these in you, rather my recommendation is to ignore these "human interest" stories as much as possible. It's fine to be informed, but these overdramatized reports suggest they're a much bigger issue than they are.

I can relate to this to an extent...I feel paranoia over five things: Home invasions, identity theft, my online identity being exposed, my online accounts being hacked, and people following me for long distances while driving.

In my case, the fear over home invasions happened because of one in High School. The perpetrator was a then-close friend of mine. He made off with all of my video games, video game consoles and half of my father's DVD's because a relative mistakenly left one window open. This affected me for years, and still does to a certain level...if I'm awake in the middle of the night, any "bump" is enough to make me take notice.

The ID theft/hacking thing may be a result of the media. You hear this crap nearly every week on the news...it's enough to make everyone a little uneasy and has made me forget every overcomplex password I make for every website. I had a small incident happen during college that was easily handled by my bank before I discovered it'd happened. Ever since then, I've tried to be as cautious as possible but I still get uneasy.

The online identity is a big deal to me as I function on multiple sites under different usernames and try to keep things separate. I run a web show, so if my real name were to get out, either through some coincidence or some troll trying to be silly, I'd lose my mind...so I took massive steps to make sure my real life and online life were totally separate.

Finally, I also have an issue thinking cars are "following" me...but this could also be inspired by news reports of random perpetrators tailing victims for miles. When I see the same car in my rear-view mirror after a while, or if I'm going the speed limit and the car behind me is at 3-4 car-lengths behind, I start getting suspicious. In 100% of the cases it's all in my mind, but if I start getting concerned I often turn down a side street and let my GPS get me back to the main road.

Anyway, as others have said, the best thing to do in this case would be to discuss this with a professional. I am no expert on any of this, therefore I can only compare and relate to my own experience. Whichever method you choose of sorting this out, I hope you can eventually find some clarity and overcome these fears.
