I'm so sorry about your diagnosis, Ryan. My brother was diagnosed in May, so I have a bit of an idea of what you and your family are feeling. It must seem really overwhelming right now, and the only advice I can give is to try to take it one day at a time and not think too far ahead. Hold onto the hope that your illness will be slow to progress.
The shock of a diagnosis is terrible, but it will wear off after you've had some time to adjust. And you will find a community here of wonderfully supportive, helpful people with a wealth of knowledge to share.
