Depends on your state but usually at 16 you can leave and officials cant do much about it unless you go back home on your own. I suggest dont leave home though I did that and it was so hard to live on my own so young. And if your situation is so serious to the point where you do feel you need to leave do your research find a youth housing or youth shelter and apply for a court hearing to be emancipated but make sure you know what youre doing. School, Work, Bills isnt all that fun.
