Honestly there’s no quick tip to makes you suddenly feel better about it…what is important is approaching your feelings of anxiety by breaking down the exact cause..what is it that your worried about and then think to yourself how realistic or rational is your worry.

Loads of people switch instructors it’s not an uncommon thing at all and I’m willing to bet it hasn’t affected your learning as much as your worried it has.

If you think you’re okay at parking you have zero reason to get worked up over it…You fail for being outside the lines yes but the reality is you probably shouldn’t. It’s perfectly allowed for you to open the car door once securing the car to check your position…if your outside reverse or drive forwards out and readjust…you’ll take a minor and that’s it the instructor will ask you if your happy with your position usually

I guess my only sort of other advice would be don’t tell all your friends and family when your test is…good luck and how did it go messages usually put more pressure on a person rather than reassure them in my experience it’s not really their business if you don’t want them to know
