Why must people keep bringing up the past....... what is in the past shld just let it be. Please stop digging and opening my old wound.

And why cnt ppl just try to understand me more ? Im trying but im very stressed up at work.. why cnt ppl just ask me if everything is ok before any assumption? Im stressed. And if im stressed..... i rly dk how i look like to others.. my mind is full of other thoughts.. please just..... understand....
