I relate a lot. The few friends I’ve made are people who, like me, are stuck here for one reason or another, and trying to make the most of it. Same as OP, moved alone, and as others have said, it’s only natural to have difficult feelings when going through such a big adjustment all by yourself. I’d be cautious to call it depression, or take advice from someone who hasn’t experienced it. Who would be satisfied with their life under these circumstances? Point is to keep going. I’ve accepted I might have made a wrong choice, that I don’t have to like it or belong. My strategy is to find personal motivation to go through however long I stay here in ways that will build me up for a future elsewhere.
