Goodly morning Tyler...

Well Tyler I have a little flying experience, about 65 years and 3 Log Books full of memories...

I was a check pilot and Instructor on DC3s, 4s, 6s, Consolidated PBY5As/Canso, a few DeHavilland Aeroplanes also.
Almost every First Officer going from the right to left seat were just like you, worried they were going to make mistakes.
I used to track the aviator down before the check ride and go for a tea, coffee, etc. and start talking about anything but aviation and the check ride.
By the time we got to the aircraft, we were both equals, both aviators...just like in your case.
Do not worry about the amount of hours you have, your instructors will tell you when you are ready and that is all that matters.
A good idea is to run through a check ride with your instructor.
The most important thing is to relax, be yourself, the person that will be doing your check ride is just like anyone else, they put their shoes on one at a time...

Look them right in the eye when doing your check ride, perhaps all you will see is your instructor...

Of course if they are the opposite sex of your instructor try not to laugh out loud...

Education and experience are what make an aviator, you have about 40 hours of experience, far more than the average person walking down the sidewalk.
Education, well every flight will be a learning experience, just like this check ride.
Savour it, relax and just do what your instructor showed you, nothing more, nothing less.
One last thing, I always told my students to look at the person doing the check ride as a student pilot or friend and you are about to teach them something.
That is right, you are about to teach this person what you know about flying and do it.
