Is there something wrong with me?

Worried, don't know about that, but I mean, the fact that you can see how it's negatively affecting your life is a good start I think. When I was little, I was CONVINCED zombies were going to storm my hour and would be up for hours peeking out my window to try and catch them coming down the street, so I guess I kinda get where you are coming from. I don't think it's a bad thing to "over think" things, just as long as you don't let it prevent you from enjoying yourself
