This sounds like a very difficult situation. It's hard even to address. I am isolated myself which I do because I feel like I don't fit in anywhere. Not that long ago I had to cut myself off from most of my family because they were dangerous to me. I had to threaten to bring the law in in order to accomplish this. None of the non-dangerous family members talk to me about anything but their own lives. It feels like I may as well not even exist. The people that are in my life all have friends and family and are busy. Everyone I know is an acquaintance, not a friend. It is very lonely. I don't see a way to change it because I'm very emotional and that tends to repel people.
This probably doesn't help much; you're not alone in being alone though.
I would not have the courage to move to another country.
It helps me to just get out and walk.
I cry a lot because I feel lonely.
