When you are disappointed, especially at not reaching a goal, how are you responding? For some, they react internally “Because I did not achieve this, I must not be worthy (of love, security, whatever).” Now, this might not verbally run through their head (or perhaps it does!), but it is emotionally felt.
A Perspective on Fear
When it comes to doing things psychic or otherwise considered “paranormal” or “unordinary,” there’s always a possibility of encountering that essence inside that leaves one crying out “Noooo!” A lot of people experience this when they are forced with public speaking (not necessarily paranormal, but outside a perceived comfort zone), or also having to address an emotional issue with a partner, etc. In technical terms, we call it Fear. And as I eluded to in the latter sentence, it is a form of rallying against going outside your comfort zone.
