Anxiety

I am suffering from a severe case of anxiety right now.  I thought I had my anxiety under control earlier today but then I took a practice test for my licensing exam and did not do very well.  I barely passed and that set me back a ways with dealing with the anxiety.  Everyone keeps on telling me I am going to be fine and will pass but I am so worried if I don't.  I know I can take it again which makes me feel better but I have to have the licensure to keep my job.  I realize that being anxious does not help with my performance but it is hard to manage.  I will be so glad when this is over!  Once I pass the test I will really feel like I am done with grad school. I need some divine intervention here and to feel the presence of the Spirit.  What if every one's confidence in me is misplaced?  Maybe it would have been better to not have taken the practice test.  I am really tempted to take the 85 dollar practice test on line right now as it is the approved test curriculum.
