Been there, no fun for anyone! I hope it gets better for ya!
A piece of advice would be remove yourself if at all possible. Also, if you are able, tell your parents you heard them fighting in a very soft way, mentioning that you can still here them even if it is in the other room. Don't get angry or yell at them. You are still their kid and your parents should feel embarrassed and awful about arguing because they love you! At the very least they'll move their arguments away from you and maybe even avoid arguing when you are around.
