It's hardly a wise solution to, as you are, try to run away from these problems. There behavior is not excusable, but it also certainly isn't something that you should take on a superficial level. Yes, it is bothersome, stressful, and hurtful to be in a household of constant yelling and conflict, but at the same time you're not the one in the arguments. Just imagine how they must feel, day in and day out fighting within a person they planned to, most likely, spend at least a good portion of their life with. Imagine the energy it must take to argue as such. It's not that they don't care about you, more likely than not they are just too preoccupied with their own quarrels they simply forget how you must feel in all of it. But then you seem to be doing a bit of the same.
On the other hand, of course, you should be in a calm household. Everyone should. You need somewhere to be safe and, if for a temporary amount of time staying with your friend is that safe place, Godspeed to you. However, please be mindful that there is a large margin between collecting yourself and running from an issue. You can't always run from your issues or barricade them outside of your door. Too many people seem to think these days that a problem will just go away if they ignore it. Going through a family that parts as such is never easy, but you'll make it. It may only get darker before dawn, but it makes you appreciate the morning sunrise so much more. Best wishes, dear.
EDIT: I do wish to make it clear that I'm not advocating you leaving home, and I do advise against it. But it is up to you. If you decide to leave, it would be best to stay at a friend's house, but you really should consider the entire situation before taking any drastic action.
