As someone who passed on their 6th test (25 years between tests 1 and 6, though I did have a massive break in between
) I would say just take the test.
On my first test, I burst into tears because I couldn't do something and just got overwhelmed. But that was the worst thing. No one died, and doing badly on that test now is totally irrelevant because eventually I passed. If you fail, you fail. At least you tried. And then you know what to expect, and next time you'll do better.
Just to say I cried also before my 6th test. I couldn't do my manoeuvres the day before, I had a dodgy tummy, I felt stressed to the eyeballs. My partner said well don't do it then. And I thought what a waste of money that would be, had a banana and tried to calm down. And then later that day I cried again because I passed.
I can honestly say that moment of passing my test was one of the High points of my life. It's up there with the births of my kids and being the first person in my family to get a degree.
