It's interesting that you make this point.
The very difficult thing with this is that we are trying to do something at the most difficult time to do it!!
I have found that there is a way to do this in a very controlled manner, when we are in a safe place, which actually recalibrates the mind to realise that nothing bad will happen. This recalibration actually dissolves the fear forever!
If you would like to know more about this technique then let me know and I'll send it over for you to take a look at it.
