I'm a worrier too. Always have been. And probably always will be.
The thing is, you can't force yourself to forget about
your troubles. You can only force yourself to think about
something else, and by default that makes you forget about
your concerns for however long.
The one thing I know for sure is that internet research has a point of diminishing returns. Once you are sufficiently informed about
your condition and the treatments and things to watch out for, further reading will only serve to scare you off.
Several months ago, one of the moderators said something to the effect of: "People who get the surgery and have no problems rarely show back up on the internet forums to tell their side of the story. So mostly what you see are the people that have had issues and that leaves an impression on us that a larger portion of people have issues than really do."
That makes sense to me. Hopefully you can take some solace in that. If not, those birds iPoop mentioned are pretty darn cute. That might do the trick for a short while.
