If you fail you still have:
The only pressure you may be feeling is the pressure you have put on yourself. Nobody at the testing centre will care what your score was, they will forget about you the moment you walk out.
I would recommend not telling work colleages or too many people you are taking the exam so you don’t have to debreif them all. One friend of mine at Cisco passed the entire CISSP and never told anyone at work (apart from me).
We all fail exams or other things in life so get over it. Re-book the exam, learn any lessons you need to and take it again.
If you build it into some terrible monster then you will only make yourself a bag of nerves.
