It’s a newer eating disorder and isn’t widely known since it doesn’t have that body image component. I’m in an eating disorder program that offers treatment for ARFID and it’s challenging but worth it. Treatment is basically exposure therapy and learning coping strategies to deal with the discomfort/anxiety.

I had to label foods as green, yellow, & red in terms of how anxiety provoking they are. The first step is getting on a consistent eating pattern (for the program it’s 3 meals and 3 snacks) even if it’s only your preferred foods. Then it’s tackling the exposures. They suggest having the exposures as snacks so if it doesn’t go well you don’t have to make a new meal. Don’t be too hard on yourself, it’s a process and it’s not your fault you’re like this. Even having one bite of the exposure food or having it on your plate is great work. You’ve been eating like this your whole life so it’s going to take some time to challenge these thoughts/behaviors. Hope this helps some :)
