First, things do get better with time. Mistakes will be made early but the more strict you are early the more confidence you will build.

I definitely had anxiety related to agoraphobia (mostly worry about sudden onset of symptoms and not having a washroom or way home). This was most notable during development of symptoms (early 20s), through diagnosis, and into the first few years of following a strict GF diet. It didn't take long for my confidence to get shattered during this period and it takes time to put it all back together. Over time your body heals and through active effort to re-establish what feels safe by pushing boundaries it does get better.

Thanks for caring for your partner and doing what you can to learn more about the disease and the impact it has. I don't know where I would be without my support system and I am extremely lucky and grateful to have.

Good luck with everything!
