I think the key to eliminate, or at least to reduce, this negative emotions is meditation. I am naturally a thinker, a man who continuously analyse something.Before starting to meditate daily, in my case every night for 25 minutes, my mind was in constant discussion and giving feedback on any conscious or unconscious arose. This was happening now more than three months before I started to meditate constantly. But since then things gradually changed and I can say that my mind is quieter than ever. This does not mean I no longer think, it just means that my mind chatter disappeared. And now, to get to the topic, it seams that this missing mind chatter has led to some control over negative emotions.
In my opinion these negative emotions derived from one single primordial emotion, namely "the fear". And fear is nothing but an imaginary construction of something which is not, something that might happen and certainly this fear sensation occurs because of the way the mind operates overly analytical.
So meditate steadily, I think that you have only to gain and nothing else.
