Hi Jen and :welcome:
Sorry you had to find yourself here but on the upside it is a fab place for support and info. My daughter was diagnosed when she was 14 and I hear you loud and clear on the relief at finally getting a diagnosis, it certainly has the puzzle pieces falling into place doesn't it!
Roo didn't through puberty until she started to receive treatment and then bang! Over the next 18 months the change was amazing.
A diary is a great idea and we have a guideline in the wiki..........

In Roo's case she was undiagnosed until she had emergency surgery that resulted in a bowel resection, she has been in remission since then. She had a large amount of bowel removed and was left with short bowel syndrome but over the years she has come to settle on a vegan diet and this works well for her and the issues she has.
My son has just been recently diagnosed and we are still in the process of sorting things out. He was diagnosed very quickly but nothing seems to be going according to plan so we are still very much in the thick of it. I thought we would be able to avoid going down the path that Roo did but it isn't panning out that way.
Both my kids have CD in the ileum and depending what type of CD your daughter has treatments may vary. It's lovely to have you here advocating for your daughter and please keep us posted on how things are going. Any questions just fire away and remember, there's no such thing as a dumb question or TMI!!!
Good luck and welcome aboard!
Take care Mom, :hug:
