Now that you know you have Crohn's, you can take the first steps to getting the support you need (and this site seems really great!) I wish the very best for you.
Since I'm rather young and don't have Crohn's myself, there's only one piece of advice I feel respectful giving, but I hope it helps nevertheless.
To you and everyone else here with kids, try not to feel inadequate if/when your children do not understand or get mad at you because of your symptoms. I moved in with my boyfriend when I was 18, and his mom has Crohn's. I came from a bad house before that, and I didn't understand my own emotions, therefore, couldn't understand the feelings of others very well. Everyone matures at a different time in their life, and having good moms like you ladies helps a LOT. Just by saying you feel bad for worrying them shows you care.
But when they become more emotionally mature, they'll understand your problems better. I wish I could go back to my 18 year old self and say "Hey, cool it!" I didn't understand. And I didn't understand my boyfriend's mom's condition until I was ready to put my own problems aside to help her. She helped me grow up, from teenager to woman. She's an incredible parent, like all of you.
Your children will come to understand someday when they're more grounded themselves. Until then, try to be patient. My lover's mom was and is, and now I'm here at a support group a few years later; I'm making an effort to make it up to her by understanding Crohn's so that I can take care of her, and one day, her grandchildren who may be at risk.
My bf's mom tells me sometimes it's hard to believe in herself. But know that no ailment can stop you from being YOU, or loving your family. You are no less a person than you were before you were diagnosed, and you deserve no less <3
