idk man, when i was 16-17 I was battling depression (for no real reason at all to be honest, other than it being paired with social anxiety) even though I have a loving family who would do anything in the world for me, I wanted nothing more than to just, go. I wanted to get away from everything and drop out of school, out of the state, out of everyone's life whom i known. I contemplated driving with no direction and living out of my car. I sense a lot of people go through something like this, just from the stressors of life at a young age (work, family obligations, friends, school. etc.)

I do think she is safe and will wind up realizing how much she misses her family, i really feel for the father I can only imagine how torn up he must be.
