As I offered in a previous post, FEAR is about a "real and present danger". It is not worry about something that "could" happen - it is a dreadful feeling about something that IS happening.
This distinction is key, for our purposes.
To be clear, the physiological and biological mechanisms of the experience of "anxiety" and "fear" are, for the most part, quite similar. However, if we do not make a distinction between these two experiences (anxiety being about the dread of what "could" go wrong while fear is the dread about what IS posing a real threat), we cannot deal with the situations in an appropriate way.
As we've discussed, we help children walk into, through and out the other side of anxiety. We do NOT do this with fear.
Consider the times during your childhood when you have felt afraid - truly afraid - about something that was happening in that moment. Maybe it was a large dog barking directly at you, a peer threatening you with harm if you don't comply with their requests, or an angry adult issuing threats of corporal punishment. This was real fear and you did not need anyone to help you "walk into it".
What did you need?
