You might want to check out Stoicism, the philosophy, which has a lot to say about emotions. How to Be a Stoic: Using Ancient Philosophy to Live a Modern Life by Massimo Pigliucci is a pretty good intro. You can also try diving right into original sources like the Meditations of Marcus Aurelius, or the Enchiridion by Epictetus, or something by Seneca. There are many translations for all of these.

The book "A Guide to the Good Life: The Ancient Art of Stoic Joy" by William Irvine is a good book on Stoicism that provides a good practical perspective on using the approach in your life.

Also, not on Stoicism, but "10% Happier: How I Tamed the Voice in My Head, Reduced Stress Without Losing My Edge, and Found Self-Help That Actually Works--A True Story" is a book by Dan Harris, a news correspondent, bringing philosophical approaches to everyday life.

I was going to suggest the same. Stoicism as a practical life philosophy may help a great deal. William B. Irvine's "A guide to a good life" gives a practical intro and advice.
