Your amygdala (see link for scientific explanation) can store feeling memories of events before you can remember consciously.
For example: No one can remember consciously before the age of two, but before that age you store many memories in the feeling part of your brain, the amygdala. Just being left alone too long as a baby, can feel like a life threatening situation because you are totally helpless at defending yourself or even feeding yourself.
These feelings get stored in yoru Amygdala and can re-trigger in the future whenever anything remotely similar comes along. Just being alone can trigger the baby’s feeling of “alone equals life threatening situation”. These irrational feelings can cause chaos in our lives. TheReleaseEffect.com can help you reset these old irrational feelings.
