I'm sorry you are having to cope with all of this arguing. I'm an older person now. But many years ago, when I was growing up, I recall my parents fought a lot too. I can vaguely recall one incident where I tried to intervene. My father put me in my place quick-like & I don't think I ever tried that again.

I don't know as there is a lot I can suggest with regard to this. My personal opinion is that what is going on between your parents is between them. It has nothing to do with you directly. So my thinking would be that the best thing to do is to simply stay out of it, perhaps even leave the house for a while if possible. I remember riding away from home on my bicycle on one of my birthdays when my parents were arguing. Whether it's right or wrong, my experience tells me there's really nothing a child (even one of 17) can do to intervene when parents start fighting.

Having written all of that, here are links to 4 articles, from Psych Central's archives, that (hopefully) may be of some help. The first article is by our host Dr. John Grohol, Psy.D.:
