DD is doing beautifully in high school. No anxiety or panic. It's amazing what a difference a few years makes. I did speak with a therapist who was going to see her the night before her first day of school. She was still fine that day, so I called and told him she was doing well and didn't feel a need to come in. He said he was happy that she was doing well and didn't need to see him. He also said he didn't see the need to push her to come in if she didn't feel the need to. He did say that he will always be available should that change, and I've made it abundantly clear to her that she can see him whenever she wants, and for whatever reason -- peer pressure, stress, anxiety, to complain about her parents...
I still shake my head in amazement at how easily she's adapted and how comfortable and confident she is now. Of course I feel like the boy who cried wolf, but I really felt the need to be proactive and to be prepared in the worse occurred. Isn't it just like kids to make you look foolish at every turn?

I'd much rather feel foolish than have her beside herself with stress.
She's also begun signing up for extra-curricular activities and really participating in everything the school has to offer. I'm so proud.
Of course we're dealing with other teen-related issues, but nothing outside the scope of normal -- pushing boundaries, sassing me, wanting more independence than I'm willing to give her, but I look at all of that as a blessing and am so grateful she's feeling well enough to push my buttons.
Thank you all once again for your concern, compassion and the benefit of your personal knowledge and experience.
Forgot to mention: the therapist recommended an out of print book for DD, but I was able to find a newer version. Can't remember the name, but if anyone is interested I'll find out what I get home tonight. I also bought her a teen anxiety workbook. I don't think she's spent too much time with either of them, but I do think she's thumbed through and found a few CBT points that helped. Also, it seems her best friend was more panicked than she was, and that really seemed to put her in a position of helping someone else. I think she knew someone had to the more confident person, and since it wasn't her best friend (who usually is more confident) she stepped into the role.
