Interesting syncronicity, I just bought 2 books from a Tibetan Buddhist perspective. One is by the Dalai Lama and Parl Ekman called Emotional Awareness
and the other by Pema Chodron is Taking the Leap: Freeing Ourselves from Old Habits and Fears
. I consider myself an all around Buddhist, but Zen is my main focus. So, you might want to think on it before you follow anything I say. It was mentioned to be with the emotion. What this means from a Zen and I think Tibetan and possible even a Theravadan perspective is that you don't try to change what you are feeling. So, if you are anxious, just be anxious. Put all your awareness into that emotion. Recently, I received some hard news and i "needed" to cry. So, I did, but it didn't last long. If i had tried to suppress it, it might have lasted longer. Pema Chodron has talked in several of her books about how the usual thing is to try to escape whatever difficult emotional state we are feeling. So even meditation can be used as a means of escape. Fortunately though, it has been my experience that practice brings up painful memories and mindstates at times. If you only want the good states, you will try like crazy to recreate them and that can stifle real progress on the path.
Well there is my 2 cents. Whatever happens, I wish you well and much happiness and many years to practice this wonderful path.
