Thank you for the responses.

If she threatens suicide again we're taking her to the hospital.

I'm just a wreck! I can't sleep at all. I'm really stressing. I'm so disturbed. She's only ELEVEN. That's so young to be suicidal.

She had a panic attack at school too and went home early. My husband has panic disorder, but he's unmedicated and has learned how to cope using CBT skills. We're hoping CBT will help our daughter.
