Identification with Negative States

I have noticed a certain phenomenon. When I am in a positive mood, I don't identify with the mood. I don't cling to it, I am aware of its impermanence. When a negative mood occurs -- as anger, or despair -- I completely and absolutely identify with it. I *am* this state, I believe it. I do not recognize its impermanence: I think about this mood as if it won't end. Seemingly, negative moods make me unaware of non-self and impermanence, based on what I said. My questions are: **(1) Is this a question of aversion? How can I avoid being phased by negative states?** **(2) More specifically, how do I avoid identifying with such negative states, and how do I recognize their impermanence *when they occur?*** **Basically, I know one ought to observe such states mindfully, but in their immediate occurrence I get caught up, I am motivated to act or speak in a negative way.** Thank you.
