Need help, unhappy

Im really unhappy with where i live... its even gotten worse to almost suicidal thoughts & running away. I live in nc currently.. its not anything terrible like im getting raped or anything.. just really unhappy.. courts demanded me to live with my father & hes not a understanding person.. im a teenager i dont do alot & rarely go anywhere.. nobody is rarely here & nothing ever goes right.. does anyone have any ideas for how i should bring up to my teacher about it? ( guidance councilor is no help )
