Here is a smart way of clearing the fear before it starts to populate your mind with horror stories and catastrophisation. As a constant practise, before long you will be experiencing sustained joy, confidence and peace.
Ask yourself the question, is there any fear (in my body)?
The answer is always yes ~ if you are in a human body there is bound to be a certain level, until you become enLightened.
On answering Yes, that would appear to cause the fear to rise up through the body on the in-breath.
As it does so breathe it into the heart centre.
Where it disappears.
Simple, and immediately freeing.
