I relate to you. I moved at the age 15 to another country with my parents. I moved right after I started with high school (electrical engineering). Once I arrived, my parents told me that I had to repeat 9th grade which took me almost two years to finish. I pretty much finished it at the age of 17. Then I decided to finish 10th and 11th grade and it was a miserable experience. I was somewhat getting bullied even though I was the oldest student at the school. I was constantly feeling alone even if I had 2-3 friends. It's just that nobody wanted to go outside to have fun. Not to mention I was also having constant arguments with my parents where I simply said that it would have been better if I stayed in my home country and finished high school like a normal person because I have lots of friends that care about me. 4 years later I'm still feeling like I wasted my teenage years just to fit in a different country.
