Getting empancipated in Washington State

Hi im 14 yrs old i will be 15 in march, i have my own job and could support myself. I want to be imancipated but my parents dont agree that i am resposible enough. My dad beat my brother who moved out at 17 and now is in the army, and my sister was highly depressed and is never home because of my familys situations. i want so badly to leave because i am not treated with respect and am pre judged, and i feel more safe at school than i do at home. So if any one knows anything about the Washington imancipation laws, like (how much it costs, and how long it takes) plz plz write back to this :?: :!: :evil: :cry:

Under Washington state law you must be sixteen to petition for emancipation. You may review the statutes here.
