Pema Chodron is my go-to person in terms of looking at how to deal less than positive emotions from a buddhist perspective. In DBTH she interprets ancient text into contemporary situations, encouraging the listener (its an audio book)*not* to take her word for it, or the words from hundreds of years ago, but to consider each point and explore its truths on one's own.
Chodron is funny and honestly I'm not sure who wouldn't find something of value here, unless you always handle anger, jealousy, resentment, etc, in a perfect fashion. One of the key points for me was (and always is when involving Buddhist discussion) - learn how to embrace change and not to have your feathers ruffled. There will always be things happening that you're not going to like, people wronging you, whatever the case may be..and you can run from that or get someone back twice as hard (my personal downfall :)...but the key to having a calmer, more open and rewarding existence is to look at those negative acts and wonder "how did that person get like that?"
Another important point was "facing the detox". Addressing long-used negative patterns is not at all easy. But just like a physical detox, it starts out pretty rough and only gets easier with time.
I felt like I wanted it to go further than it did, I think this is partially due to the fact that it is a recorded seminar so does not have the depth of a thoroughly discussed hard copy book.
