Yeah its gonna be stressful and I can't tell you it will go well, but it might. Adventures like this are good for people your age as well. Having a plan for if it goes poorly is a good idea. Video calling beforehand is generally wise because it can guarantee you aren't being catfished and that you vibe in real time.

Go in expecting a good time and prepared to show a good time. And while it sucks if irl you don't get along it's ok. There's a saying in America that bad times make for good stories. Your teenage and young adult years are for adventures and building experience. It's scary and exciting and no matter how it goes you'll probably be glad you did it when you're older.

My story isn't even the only great time I've had with internet friends. If I'm near anyone I know these days I'll at least try to swing by for a meal.

So what's most likely to happen? Probably a generally good time. Nothing life changing in any direction though your age is one in which life is quite malleable and it's downright common to have life-changing experiences at that age. But it should be fun, and you'll likely stay friends. It's quite likely the friendship will be different afterwards but not worse, just closer and informed by how it felt to be in the same space. Inside jokes are likely to happen also.

Thanks, I'm sad it's needed but also excited and I choose to maintain hope that good will win both here and abroad.

Best of luck, have fun on your trip
