It is the natural state of an Expanding Human Being to experience no emotions for hours, maybe even days at a time.
Emotions are a response to life, to danger, and should be momentary and responded to. Not the continuous torturous emotional states you are experiencing.
When something evokes a strong emotional response, fear, disgust, there is something you need to deal with. Something that is out of whack, something that is unfinished business, suppressed, swept under the rug, and threatens to throw you out of you equilibrium, your peace of mind.
Of course, for most people life is going from emotional turmoil to emotional turmoil, but it doesn’t change what I said: emotional turmoil is an indication that there is something unfinished, and it needs to be finished.
