How do i get emancipated?

i am 17 yrs.old.... and i am 7 weeks pregnant.. n i am considered an orphan under the state of Ohio... but live with my legal guardians (my grandparents) how do i get emancipated... or how can i go about it... b/c i do not want my baby living here... n if i stay i will have no support from this side of the family.. but my grandmother.. has every other weekend visitation.. is there any way i could just go live with her without getting a lawyer.. n no permission from my stupid legel guardians

Have your (other?) grandmother petition the court to revoke the present guardianship, and to appoint her as guardian.
