Congratulations on head-on tackling such a tough problem! I wish you the best of luck as I"m sure it is not easy. Wanted to comment -- I'm not sure the extent to which this will be useful or relevant (so forgive me if its misplaced). I was interested in meditation (and to some smaller extent, buddhism). This book is short and generally well written from a buddhist perspective but may be of particular interest because the author previously suffered from panic attacks and believe's his use of meditation allowed him to control them: https://www.amazon.com/Joy-Living-Unlocking-Science-Happines...
