what can I do?

Haiz... my parents are currently quarrelling:( My mum is super upset, and i think she's going to breakdown soon:( I don't know what I can do. My dad is as cool as cucumber while my mum is trying to communicate with him but he just blows her off and that makes my mum even more upset. Then my mum has no one to tell her troubles to, other than me cos my bro too young and immature. I want to help but I don't want to sit there seeing her cry and being able to do nth about it. I really dunno the full story but I think I'll side with my mum cos I know that they have been quarrelling and that my mum is always the one getting upset. I feel so helpless. What can i do? I'm only a kid. and Although i know that my mum only has me to tell he troubles to but hearing all this make me feel so frustrated and helpless.So for know, the only think I can do is pray. Pray to the heavenly father.
