The point is that she needs you to talk to her like a H not a father.
In her mind she's finally doing something that she wants to do. She is making an "adult" decision on her own independent of you. What you could try doing is to change her decision by not telling her. Show her. Show her that she's "safe" with you. That you respect her decision even if you don't think it's the right thing to do.
She wants to have a life. Show her the positives of the life you have together and give her the freedom to explore her individuality also.
If she's clinically depressed, then trust is a major factor. She has to believe she can trust you again. Also meaning that you trust her decision even if you don't want to.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
