how should i do?

i am clear that every family have their own problem,however my family problem made me feel so stress.My parent can't understand each other standing point,they always argue about financial problem.How shoud i respond to such matter?I am not intelligent girl,even i study hard but i didn't study smart,i really hope i can achieve my target in getting flying colour result in my exam.At the same time,my parents had quarrelled.This time is more worsen but i still can't end up this quarrel after i had tried for many time.What should i do?Ask myself ,is nothing which i can do because this is my parents's problem,they can only solve it by themself.
