Keri,
Like you, I was a quick diagnosis. I actually laughed. I was of the mind that it was a much better thing to have than a brain tumor ( which was my first thought)
You learn to take it one day at a time. You go through the stages of grief, anger, denial, and acceptance. Then you move on with life!
There will always be someone here who has been through something like what you are going through. Just come on in and rant when you need to.
Give to others when you can. Ask questions when you need to. Learn as much as you can.
Take time to smell the roses too! They are still there!
