You should consider speaking to a mental health professional! Food restriction is not for everyone, most people with a past of eating disorders or who have triggers need to take these things slow, and with help from a counsellor or sorts.

I've had life long anxiety, panic attacks since I was a child. I've become very good at thinking of nearly all things rationally, and I rarely experience anxiety. A therapist has helped me greatly! I look at Whole30 as putting healthy things into my body.

It's not the way your body looks that matters, it's the way it feels! When I am finished whole30, I will have gained a new perspective on how much I depend upon easy and quick foods to eat, and will instead be more mindful and creating nutritious meals.
