I'm half white half Pakistani too. However because our family is Muslim the Pakistani side of our culture is more influential as it is more compatible with Islam. When I was younger I used to reject my Pakistani side by refusing to wear Asian clothes or eat Asian food but as I've grown older I've grown to embrace both sides (mostly my pak side though). I recommend making some Pakistani friends. Maybe try learning more about Pakistan from your mum or by reading books, watching documentaries, watching dramas, learning Urdu?
And actually passed?
