I'll add myself as a second data point. Understanding the stoics has helped me as well.
The ancient stoics seem to have stumbled upon important insights into our nature and how to be happy. A good introductory book to stoicism is William Irvine's "A Guide to the Good Life: The Ancient Art of Stoic Joy".
Interestingly the founder of Rational Emotive Behavior Therapy, Albert Ellis, "credited Epictetus with providing a foundation for his system of psychotherapy".
