Hello Grace,
I would direct people that want to know about
Crohn's to this site.
https://www.ccfc.ca/english/info/diagnosed.htmlAlso to the right you will see Resources, you may want to browse our resources as there are book available.
Most of all like anyone who has just learned they have a chronic disease just let them talk about
how they are feeling, if their in pain, whats going on with their body and you will learn as you they through this. Validate their feelings of fear and pain and be there for them.
Gentle hugs for you. You are truly doing the right thing in looking for ways to educate yourself and your family about
this disease.
