Having trouble eating

Hello, I was on a family vacation to some places in Europe for the past few days, and really struggled to eat. Partially due to anxiety & stress, and partially because I have emetephobia and just worry about unfamiliar foods. I didn’t eat very much even though i was really hungry every day. It was just really hard to eat, it felt like I was forcing even the tiniest bites into my mouth. I got home today and have had a bit of food and a smoothie, but my family is worried about my health since I didn’t eat or sleep as much as I should have on our trip. Does anyone else have a hard time eating when stressed? Will I be okay as long as I eat more now that I’m home?
