I don't know what to do (trigger warning-numbers)

I am on vacation and I have an ed, Arfid (Avoidant/restrictive food intake disorder) I started as a picky eater, but when covid hit, I started using me not eating to my advantage. when I wanted to show I was upset with my parents I wouldn't eat (even if I was very hungry) and, they would really worry. I regret this a lot. I started needing to go to the hospital a lot because of much little I was eating, I then realized that my lack of eating was a big problem and went to a eating disorder facility that really helped me although it didn't cure me. I was diagnosed with Arfid there and that where my recovery journey started. it took about a year but I went from 55 pounds to 61-62 pounds, I felt like I was finally reaching the big goal of recovery. but then me and my family decided to go on vacation. vacation means there's nothing I can eat here because everything is different, and I probably already lost my year of progress due to my sudden lack of eating. it feels like I am back at the start and I still have a long way to go before this vacation is over. I don't know how I am going to make it through, i am always hungry here and even though there is enough food here for me to eat I just cant eat it because its all different.
