Wow, I had no idea it had gotten so difficult there. Sounds like you made a wise long-term decision. But good long-term choices often have short-term pain. So, don't beat yourself up about this transition being so difficult for you. Emigrating is never easy for anyone. You are not unique in that regard. You're in a whole new country with a completely different culture and climate and scenery. It's a massive change. Give yourself a break. It's going to take some time, but you will settle in. Just keep your head down and keep plugging away. Things will settle in and you will feel more at home.

I moved to New York City from the west coast of the US many years ago to go to college. The town I was from was friendly and safe and the surrounding scenery, physically spectacular. I found New Yorkers to be gruff, cold, and unhelpful. It was ugly and in disrepair. I was flagrantly discriminated against based on my religious background. I did not fit in. All in all, it was depressing and miserable. I stayed because the school was fantastic. After a few months, I met a couple kids from New Jersey. They were warm and friendly and showed me how to ride the subway and not get killed. New York stuff. Pretty soon, I felt more comfortable. I had a couple pals. They treated me with respect. It helped. Not all New Yorkers, it turned out, were jerks. I didn't have a lot of friends, but I have two. And that was enough.

So, don't throw in the towel. Hang in there. You will meet people and some of those people will be nice. I've spent a lot of time in the UK. The British people are fundamentally good folks. Just keep after it. And don't lose hope. At least you're not getting mugged in your old city.
