You can do this! Try to listen to songs that calm you down (or maybe nature sounds! there are websites with that), try to do something to focous and not lose your mind. Try to breathe properly, take alot of deep breaths, that will help alot. Also if you can, try to have some anxiety pills in a pharmacy or something (idk if they sell it to you in your country). It really helps alot. And in the worst case scenario find a wi-fi source ,come to Blah and inbox me. I’ll be right here for you!
Also about Spain, you’ll like it. I’m portuguese (so I’m neighboors with Spain haha) and it’s a cool country so don’t worry
Try to have fun and forget about mean and stupid people.
I hope I could help in some way!

Try to relax and calm yourself @justagxrl, I’m sure you’ll have an awesome time in Spain, try to focus on all the wonderful things you will do, don’t let horrible people get you down, there are many more nicer and compassionate people out there, keep smiling and don’t give up, things will be OK, you can do it, I’ll always be here if you need to talk, message me anytime if you want, my inbox is always open, stay strong, you are never alone (hugs)
