I was searching a term on google to learn more about my specific problem, and the third or fourth link on the search page was a place to get to MY forum topic on pc.

I'm a little freaked out by this. Some of the things I've posted about could easily be recognized by my friends (and non-friends) and some of these "friends" know I have this certain specific issue. There is a chance they would look up the term click on the third or fourth link and I'm found out and embarrassed for the rest of my life. I don't want to be found.. Is there a way that I can hide my posts from google or any search engine or am I screwed because I decided to share a little on the internet?
