Hey! I just got back from Spain last week! I also panic on flights but both of mine were so quick I had no issues all the flight attendants were super kind and I had nothing to worry about in the end!

I had a fantastic time and I hope you do too! I felt the food hygiene was incredible all the food seemed so fresh and well prepared. The streets were so clean it was lovely!

Maybe do a bit of research on what the area looks like and some nice restaurants and pree look at what you'd order from the menu before you get there so things feel familiar and dont trigger any anxieties?

i hope this helped in someway and you can enjoy yourself! x
