Frustration being that it is just not working, and you need to get out of your head, pull out the mental machete and whack your way to clarity.
-In this case, it is great to have the feedback, because the questions and the comments might help you to approach from a different direction. Re-strategize.
it is good to feel and pay attention to that emotion.
