I only have the road test left and I'm so nervous (Please help me)

‌I'm a late bloomer trying to get my driver's license.
I got 100 on both the written and the driving course tests, but I'm so nervous about the road test that I haven't even applied for training yet.
I studied really hard for the written exam on my own (I went through 1,000 practice questions three times haha).
I registered at an academy while doing the driving course, but they didn't teach as well as I expected.
It's near my house and they advertise a lot, so I registered there—even though it was more expensive than other academies—just so I could do the road test on familiar routes.
However, most of the instructors are grandfathers in their late 60s to early 70s (they smoke and use informal language by default ㅜㅜ),
and the cars were so old.
After 4 hours of practice, I came home and watched even more YouTube videos as prep,
memorized the formula for perpendicular parking, and my husband patiently taught me the rest, so I passed.
Now that I have my learner's permit and want to practice the specific routes, I'm scared, so I went to a driving zone to practice, but
it's a total mess.
Staying centered in the lane
Increasing speed with the accelerator and controlling it with the brake
Getting the right-turn signal, coming to a stop
Even keeping my hands on the wheel while using the turn signal doesn't go the way I want...
But the mix of excitement and feeling lost is so overwhelming that I can't sleep haha.
I want to stick to the basics, so please share any tips or things to watch out for.
ㅎㅎㅎ Actually, I just wanted some encouragement.
