I would say yes since that's what I'm going through right now! I think you should be proud of the progress you made, and use it as proof that you can definitely get back to a calmer state of mind again. Appetite loss from anxiety is one of the most annoying and scary symptoms I go through, too. I used to be on a prescription appetite stimulant (Periactin) which helped me out a lot. But since I can't get any new prescriptions at the moment, I just let myself have some days where I don't eat and try not to freak out too much since I do have to eat again eventually. Try to keep yourself hydrated so that even if you can't eat at least you're getting enough fluids. Give yourself time to rest and recover during setbacks, don't be too harsh on yourself since you're trying your best and any progress you made still counts and is worthy of being proud of. You've got this!
