There are different rules for under 18.

My T is very into privacy though she can to talk to my pdoc she has never. For my T It's usually: Why? What steps are you making for x not to happen (happen again)? When is your next appointment with T or Pdoc? I would sit down and write a crisis plan before you go and take it.

I would seriously talk to your T. Especially since you have guilt associated with it. I would tell her that I am willing to go on medication to treat my mental health? but only if you truly will. Say it wasn't a suicide attempted. Best of luck.
