I hoep I'm making sense - I'm still in a bit of a trembly whirl. Its a shame because I was in such a good mood to that point.
Try the following.
Close your eyes. Recall a time you felt fully calm, happy, and confident.
Relive the experience in your mind. Run through it several times.
Each time focus on a different sense. First relive the positive experience by seeing it through your eyes.
Next as if you were watching yourself on a movie screen.
Next relive it but pay attention to what you heard ans sounds.
Next relive it paying attention to the sensations of your body and movement.
Relive it one more time. But this time focus on the positive emotion that is the strongest (i.e. calm, happy, whatever..). Focus on your body. Somewhere in your body is a sensation that is normally unconscious. It's a sensation in the body of the emotion. An example is when you feel sad you get the sensation of a lump in your throat. Happiness and all other positive emotions have a physical sensation in your body as well. Find it. Is it in your chest? Or your tummy? Maybe it's in your head? Relive the experience while focusing on this sensation and try turning it's "volume" up.
After you do this you should feel fine.
