I did spend a lot of time online researching. I started out at the ACS website. I also spent a lot of time on the website for the hospital I'd be going to. It took awhile to find the What Next website. I wanted to find out what my disease was, what my prognosis might be (a dangerous thing, especially not knowing what stage I was -- but also figuring I'd be 3 or 4 since nodules were found in the hernia sac during a hernia repair), freaking out about prognosis. Bing was my friend instead of Google. Who knows what sites I was perusing while plugging "endometrial cancer" into the search engine. I also spent a lot of time looking at my company's internal website to figure out FMLA stuff -- how long I could be off, what I needed to do, etc.
I am a research oriented person, so I didn't stick w/just online. I went to the local library and probably took out most of the books they had on cancer, especially endometrial. And I hit the bookstores and Amazon.com as well. I did the same sort of thing when I lost my job. Crisis mode for me tends to be research mode.
