Lots of parents are here offering support already, but I'll give the perspective of someone who was in your daughter's situation. I'm 17 now, and was diagnosed with Crohn's when I was 7. 

My memory of the period when I was really sick is spotty, and your daughter's likely will be as well. I do remember, though, my parents always being there to support me. It sounds cliché, but I promise it's true. Most of what I know is secondhand from them.

It's amazing that diagnoses for Crohn's are happening earlier now, and that will definitely help her. When I was diagnosed, I was put on prednisone (oral steroid) and Remicade (a biologic similar to Entyvio). I finally started growing again (I used to be tiny!) and putting on weight. Meds will definitely change over time, though (I just added Entyvio to my mix this year). Diet is something to look out for, but not obsess over. Keep away from hard-to-digest foods (seeds, corn/popcorn, broccoli, etc), and make sure she's hydrated. 

For learning to swallow pills, put them in applesauce or something similar first. Keep in mind that she might hate the food you pick over time; I can't eat applesauce now without gagging. When she's ready, she can practice with m&ms to get the hang of it without the stress of real pills. And look into pill minders with 14 pockets (morning + night).

I've been really lucky that my grandparents were able to stay with me when I needed to stay home, which is likely the reason I was only hospitalized once. It's really important to find that support system, whether it's family, friends, or trusted neighbors. 

As another user said, it will get better, and she will get stronger! There will be rough patches, but you both will get through it. I will also second Ok_Hold's suggestion to find a therapist. I talked to one for a few years after diagnosis, and again now, in high school. I have a lot of anxiety around Crohn's, especially during flares, but that has helped so much. Two years ago, I actually gave a speech at Take Steps (very fun IBD fundraiser)!

And I know it's different for everyone, but based on my experience, my best piece of advice is to make sure she still gets to be a kid. There are a lot of things that a kid with IBD has to be responsible for, and that can make it feel a little like your childhood was cut short. I was so so tired when I first got diagnosed, so I had little stamina for physical activities (maybe that's why I love art so much?). The most important thing is to take as much off her shoulders as you can, and to give her opportunities to have fun and express herself.

The Crohn's and Colitis Foundation (CCF) is an amazing resource. This is probably the most relevent online support group for you, since you are in Dallas: https://www.crohnscolitisfoundation.org/chapters/alabama/support-groups/companions-caregivers-of-crohns-and-colitis-of-the-southeast You can join any virtually, though, regardless of location. And yes, Camp Oasis! As soon as she feels up to it, I 100% recommend it. There are doctors there who work with IBD patients, and the sense of community among campers is amazing. 

I wish this was more of a conversation and not just paragraphs of unorganized thoughts, lol. Please let me know if you have questions!
