I agree with the therapy suggestion. DD10 is dealing with anxiety - we've tried many things - books, online videos (GoZen has a online course DD enjoyed), counseling.

Unfortunately in our case, DD shut down during counseling and refused to go back. So I've been going myself, talking to the psych about the best ways to handle various situations. It's been enormously helpful - I now have tools to use and ideas of what to say or how to discuss things she's worried about.
