@Lynnel The present moment is all there ever is.
Don't buy into the idea that emotions are locked in the body too much. This is disempowering.
Rather, you want to become conscious that at every moment your emotions are arising as a self-manipulation. You emote to fulfill the needs of the ego, and you have the ability to cut the shit and realize: "Oh, I'm angry because my ego wants X. Oh... That's just a mental trick. Let me just be peaceful."
That won't always work, but the more conscious you become, the more you'll see how emotions are just a ruse your mind is playing on you. And you can stop that game any time just by becoming conscious of the fact that it is a game.
The problem is: most people are not aware (in the moment) that an emotion is just a game. They take the emotion seriously because they can't even imagine an alternative.
Next time you experience a very negative emotion, try to notice it is just a game. And see what happens.
For this to really start working, you have become aware of your self-agenda and be willing to face the fear of surrendering it. Most people are too selfish to do that.
The only reason emotions have any sway over you is because you want to survive. So the counter-intuitive move here is: surrender the need survive.
