Jodi,
Sometimes all you need to do is notice what you are creating, in this case the thorns, and look at it with curiosity. You contemplate on it and say "Aha, this is how I create it? This is how I make still being afraid", or whatever it is you make.
The most important thing is not to resist it and not to judge, but to accept it for what it is. Surprisingly enough, it's only when we accept ourselves as we are, roses and thorns, everything included with no rejection, that what doesn't serve us, falls away and it doesn't cause problems anymore.
I am going through the same process myself and I can tell you from my experience, and sometimes I forget, I resist what I don't like, but once I own it and accept it...it's really transforming.
Best of Luck...
