Island syndrome is when people who live on an island or in a remote area feel different or isolated from people who live in other places. Imagine you and your friends live on a small island with only a few other people. You might feel like you're missing out on things that other kids have on the mainland, like big amusement parks or lots of stores to go shopping in. You might also start to have your own special language or way of doing things that's different from people who live elsewhere. It's kind of like creating your own little world that's separate from the rest of the world. Some people might like feeling special or unique, while others might feel lonely or like they're missing out on things.
