أحسن الله إليكم I go to a Deobandi School (I think) Some of the people know I am Salafi. I go because I am scared if I tell my parents to make me not go it will cause more bad than good.Am I sinful?

I don't understand the question. Do you mean school, like where you study math, science, and language, and you get degrees?
