You say that you're pretty close with your parents, which I think is totally awesome...I would maybe try talking to them about two different things. One being how you feel about visiting, and the second being about how you are feeling.

I chose a school two and a half hours away from my hometown. It's far enough away, yet close enough just in case. But I want to get away, I need to focus on me, I need to get better.

Many schools have counseling services. I would check into that. If not, maybe see if you can get to another place to see a psychologist or therapist.

It will help to take care of you, which is really critical for being the best you can be (I'm finding that out now).

I wish you the best of luck with whatever you choose.
