I can get freaked out by "what ifs" and worrying about what might happen, too. And I often read articles or see stuff on TV I know I shouldn't, but I read them because I'm hoping they'll say things that ease my fears and give me good news. When that doesn't happen, it can make things worse.

I do agree that it can help to see a doctor if and when you can, but aside from that, I would say to try to get your mind off of it. I know, easier said than done. But if you can focus on a movie or a book, or maybe some crafts, for instance, it will ease your tension.
