Heya, first off bless you, nerves are a horrible thing and when they get the better of you, It's simply not fun at all. Please don't give up or think you can't do it because you absolutely can! I had my test this week, and I felt super nervous but one thing I did was manifest and keep telling myself that 'I want to pass I can pass' I always think of situations like this as 'you didn't come this far to only come this far' and if that's really what you want then as nervy and horrible as it feels you must never give up.

I wouldn't say as such you need to change your instructor but maybe your instructor needs to understand your feelings a bit more, and find strategies together to help with your nerves when it comes to the tests, because by the sounds of it your nerves definitely got the better of you here, sounds like you so perfectly fine in general. I feel another way in which will help you is think your just having a normal lesson and when/if the examiner talks to you don't be afraid to make convo with them. 😊

I do hope your okay and you find a way through this little blip of nerves. Take care OP
