I know lots of people who google stuff or research stuff and then develop fear/anxiety that it's going to happen to them. It's probably both, as Odee said. Which doesn't make it any worse or better than it is. If you need help with it I suggest getting the help you need, whether it's counselling, talking it over with your doc, or just spending time on here talking with others who have similar fears and concerns. Hopefully it's something that will pass rather smoothly and then that'll be it. But if it's not it will be good to have some support in place.
