I feel so lost and sad. Failed TP today with 40 points, I can’t vertical park no matter how many times I tried. During lessons also struggling with vertical parking

I went for 40 lessons so far under school. Should I give up?
Parallel park I can use mirror and markings to gauge but vertical is extremely difficult for me
Hey fifi, is this bbdc?
These are my notes for vertical parking at bbdc.
1) Position car to the right (sighting point: your right hand on steering wheel is in line with centre white line on road)
2) make sure car is straight and u can see ur parking lot on left side mirror.
3) Rem S. G. M. (SIGNAL left, GEAR to reverse, MIRROR adjustment on both sides to see ur wheels)
4) safety check (super wayang look rear, and ALL AROUND)
5) Reverse slowly until you can see (one black and one white kerb stripe of the parking lot).
6) safety check for blindspot on right, rear again
7) full lock to the left and reverse slowly, taking peeps to rear view (once or twice) and to the right. Look at ur right and left mirror that wheel is not touching kerb soon.
(don't panic if hitting kerb, correction is very impt.)
Usually my left wheel will be too near the kerb. If left wheel is too near to kerb, quickly return wheel to straight. Then reverse with straight wheel for a bit until you see your left wheel passes the left kerb safely, then full lock to left again reverse in.
If by this time u see ur right wheel is v near right kerb, return wheel to straight and stop moving immediately. Change gear to Drive, drive straight up around 0.5m, stop. Then engage reverse gear, full lock to left and go into lot again.
8) once u park and want to go out rem S. G. M again (signal, gear to drive and adjust mirror back)
9) make sure kerb is at ur shoulder before you turn ur wheel when exiting.
I hope this will help you. I know how it feels like after failing. That sense of disappointment will fade away.
I told myself it is a matter of time....be kinder to yourself!
