I have a girlfriend who is 17 years old and a junior in high school, let's call her G. Her mom passed away several years ago and she has battled with depression and bipolar since then. Her caretaker/aunt has cancer and isn't home much, and I believe her grandmother lives there as well. G does a lot of drugs. A lot.

Recently she left her aunts and "ran away" to her bfs house and hopped houses a lot, eventually sneaking out and disrespecting his aunt, who let G stay with her. This led him to break up with G. G then lost her mind a little bit and returned back to drugs and partying. Her aunt forced her into a mental hospital and for awhile she seemed better.

Until a couple weeks ago she left her aunts again and is staying with random strangers, not going to school, going to parties, doing drugs, and recently she told me she's going to Vegas with these people she's known maybe a week.

I tried talking sense into her telling her she's ruining her life but she won't listen.

Now my only objective is to get her home and safe. She may not like it at her aunts but it'd be better than her winding up dead on the side of the road. Should I go to the police and file missing persons in hopes it will get her back home?
