Anxiety in itself is a fear, a fear of an uncertain future outcome. Fears are defense mechanisms our minds install in our formative years to keep us away from what it has interpreted as dangerous. So often, they begin as a reaction to a childhood event, then over time the mind gathers and warps evidence to reinforce it’s conclusions so a lot of phobic reactions are inappropriate, miscalculations over the genuine possibility of danger.
In the UK a spider won’t kill you but if your unconscious mind has reason to believe you could be even slightly in danger because of the evidence it has gathered for you, it will send your body a physical feeling or reaction, possibly along with a little movie it has made for you showing you what it believes could happen to you, so that you take the threat seriously.
This is because it is designed to move you towards pleasure and away from pain. So you will either run away or stay and deal with the consequences. This is what’s known as the ‘fight or flight response’. Together we can work through it and update your responses because it doesn’t matter what you fear, just why you fear it.
