Hey. When things start kicking off, relocate yourself. As a teenager, you won't be any great shakes in an argument - but you will always have the right to free association, & that extends to dealing with family members.
Know your local area. If you have friends nearby, go there. If you don't, stake out a park, a playing field or a tree you can climb - somewhere you wouldn't be found or harassed. Invest in a decent coat so that you won't be too cold. Make sure you always have a loaded & charged mp3 player to help you calm down & kill time. Take a book, if you know somewhere safe & well-lit where you can chill.
You can't permanently remove yourself from the household. What you can do is learn to gauge your parents' attitudes & extradite yourself when things are getting overly heated. Ideally, you would have your own house-key to sneak back in when they're sleeping. If you don't, you'll just have to deal with them. Forewarn them by sending them a text - don't just turn up. Say "I'll be back at [whatever time]," so that they're prepped & don't have reason to call the police.
What you want is to remove yourself for three to four hours, so that they can wind themselves up, vent, reflect, & worry. By the time you come back they'll be less enthusiastic about giving you shit. Unless you're dealing with straight-up violent psychos, in which case different rules apply.
The first time you do this they will be very difficult & try to place you under a lot of stress, however, by the third or fourth time they will start to get the message. Remember that you are an independent person, & you do not have to capitulate or participate in someone else's drama.
I hope you feel better. It's a shitty world.
