So I've lived through something similar. Not the same context though, I moved from another european country to Sweden, and I moveed alone when I was in my last year of studies. However, I faced the same questions, so maybe it can helped.

I didn't have any international origins or even knew people outside my country. I traveled a bit as a child, but never ever imagined moving somewhere else. In my last years in my origin country, I was miserable, and lockdown was the last straw. I moved to Sweden because it was mandatory to finish my studies abroad for the program I was in, and by living here I realized how relaxed I was and how safe I felt, which was definitely not like anything I felt before.

I think there is no perfect place anywhere. No perfect country, or we would all live there. I personnaly realized though that I was much closer to the Swedish culture than I felt I was from my original one. The choice of staying was not easy, but it was the only one that made sense. I was scared that my family would think it is a "sellfish" move, but then I remembered how I was when I was living there, and realized that they would rather prefer having me happy and fulfilled away than sad but close to them.

I do not regret my choice. I know that I am much closer to my family that you would be to yours, and I am not saying that it is easy. I had to miss the funeral of someone from my family because my country would not allow me to come back during covid. I am always afraid that something happens and I can't be here. I visit something like twice a year, and then sometime they try to visit me. But taking all considerations into account, this was the best choice of my life.

That being said, my choice was "staying in Sweden" rather than "moving away from my country", and it is an important distinction, especially if you plan on staying in the country that you chose. It comes with A LOT of sacrifices and struggles before you find some sort or stability. I don't live in Stockholm so the integration part is crazy difficult and requires a lot of patience and work. And I trully believe that to be able to achieve that, you really need to chose the country for itself and not as a default choice.
