Good Morning,
There is a pretty good workbook for teens that I am going to recommend, Beyond the Blues: A Workbook to Help Teens Overcome Depression ~ author ~ Lisa M Schab. The activities in Beyond the Blues can help you cope with sad and difficult feelings, find new ways to make friends, and deal with conflicts.
This book is available through Amazon.com or I am sure you can request it in any of the chain bookstores. The cost is about $11.00.
Kindly,
Kitt
