I did, but...

We were inside the bathroom (it was quite spacious), but I only did it to buy some time and to stop her for a moment. She was planning on cutting her wrist, so I did it. My right had beside her head, while the left grips her weapon she hid behind her back. Fortunately, two of my classmate came afterwards to calm her while I back away (coz I'm useless at comforting.)
