I've noticed a constant refrain here advising the newly diagnosed to stay off Google, claiming that the information is often out of date and wrong.
Well, yes, sometimes it is.
But often it is not. A well-informed patient is an empowered patient, and moreover when doctors realize that you have educated yourself about your condition they are more likely to give you accurate information, rather than generalizations intended to reassure those who just want to be told what to do.
The thing you have to do, IMNSHO, is approach your google research with perspective and your rational mind in gear. If you consult wikipedia and ask about the survival stats for your condition, realize that those results are based on a cohort of people who were diagnosed and treated before immunotherapy and other current drugs were available. Simple common sense will tell you this. Don't panic. If you read articles from medical sources, look at the date first. (Not to mention the source. You can discard anything that is pushing some kind of non-science-based "natural" cure. Those people are right up there with anti-vaxxers.)
Steel yourself not to panic at every negative thing you read. Your reading and information you glean here and in other forums such as Colontown will help you find the right questions to ask your doctors and enable you to have constructive conversations with them.
If you just can't stand it, enlist a friend or family member to do research for you.
