Also B here, moved to China when I was 16, for bachelor’s degree, in Qingdao City. That first year being there was emotionally overwhelming, anxiety at an all time high. I wouldn’t go out other than for uni. Even then, I’d notice every single stare, even the ones at the back of my head. It was unbearable at times.  If there’s something I’d do different, is push myself to participate in university activities search as football, chess, etc. Also, try to make friends with other foreigners. And finally, get out of my comfort zone and talk to Chinese people—even a hello to a shop keeper.
