It is very difficult at first. No one here will tell you different. I didn't believe it when i was told it gets easier in time but it does. One day I just realized that I was no longer stressing over food and that it had become a part of me.
When you focus on what you can't have (and we all have been there) instead of what you can have it's a no win situation. If they have pizza so do I, my own & I get the entire thing to myself. If they eat pasta so do I. I think it's easier at home if the entire household is gluten-free but that is also a personal opinion.
I look at it this way - I have always wanted to be special & different.... now I am!
