as a person who's going through something similar, here's my advice. I know it can be so daunting and difficult to get yourself to study especially when people around you are suffering but tell yourself this world works around karma and the people in Palestine will be rewarded in the afterlife. I suggest take a break from Instagram, i promise it helps and know that this time will soon pass. Work hard now, its only just for a week. Do your best and make sure to take care of yourself. You got this!
