Gave myself time.  Let the new neural pathways develop and strengthen over time.  I went through the blocks, it felt impossible at first all over again.  Kept at it.  Ultimately, stuttered freely through it but saved my energy by repetition when I could rather than trying to force through, if I forced through its ok, I was becoming less and less afraid of the same thing but still stuck to repetition.  All of a sudden it began letting go out of no where with the repetitions, all of a sudden what was impossible moments ago just became like any other word.  Didn't matter at the time because I forced myself not to dwell on it afterwards either way.  But my body began getting used to that sensation and over time that which needed force began coming out through repetition, just repeating it, then that lessened and lessened and all of a sudden one day the hardest words or situations became like any other, like speaking to the wind.  Most people give up on the first sign of intense difficulty but sometimes the only way out of a scary forest is through it.  Let your body see that you survive it and are fine on the other end.  Stop dwelling on it and the less we care the sooner those words/situations become like any other word.
