CPA Exam

Well, I took one part of the CPA exam yesterday.  It went okay.  I was hoping to feel better about it than I did, but it wasn't terrible.  I had taking a different part of the exam back in November, but I found out that I failed that part.  This means I'll have to retake that part.  This is what caused me to add the additional anxiety that put me over the edge back in March.  Now I'm worried about what I will do if I don't pass the part I took yesterday.  After failing two parts of a four part exam, I will be very discouraged.  I'm wondering if I give up on the exam altogether or do I keep pushing forward?  I don't know if I'll be able to pick myself enough to be able to pass any parts.
