Test tomorrow and I’m nervous

EDIT: I PASSED WITH 6 MINORS!

So my driving test is tomorrow and the nerves are really kicking in, I’ve been on and off learning since January but really locked in on lessons in August and have clocked roughly 45 hours in the car, I still make stupid mistakes like hesitating and my parallel park isn’t perfect. My instructor thinks I’m ready but I really don’t know if I am?? It’s my first test. I have a short lesson beforehand to iron things out but I’m so self conscious that I’ll fail and I hate failing things. I know if I do it’ll knock my confidence and really set me back.. what do I do?
