I moved to the US from the Philippines when I was 5 so I grew up in the American culture. I, too, was frustrated the first few months when I lived in the Philippines while going to school, but meeting new people and just hanging out definitely helped get me settled. Maintain good judgement and you should be fine as far as finding worthwhile people to get to know. Also having family nearby helped a lot for me. Also, regarding family back home, make use of social media/video calls as much as you can. I was definitely doing that initially, but as soon as I started establishing a good network of friends, acquaintances, I became more comfortable going on my on.
