Hi Matt,
First off, I'm very sorry to hear of your recent diagnosis. On top of dealing with your son's serious medical issues.
As Kazbern indicated, you should let us know what your treatment has been so far, and how you're feeling.
The important thing I can tell you is, there is plenty of hope. Crohns varies widely in severity. You may be able to function quite normally on the right treatment plan.
I know that your son's plight must be a considerable stress for you. I certainly don't know much about his condition, but here's a story about a young girl from Canada. It might give you good reason tobe very hopeful for your son as well.
