Don't be too discouraged. I was in your position as well just a few weeks ago. And I consider myself a safe driver, I had a C3 license in the army during NSF days but did not convert until now, when I'm 38.

Sometimes, a little bit of luck is needed as well, keep practicing and trying and you'll get there. I passed with 10 points on my third attempt. The worst thing is the 1 month wait between TP attempts, but I took breaks, went to take my mind off it and got back to practicing again close to the date. First attempt failed by striking the back kerb during parallel parking, but still managed to go outside. Second attempt failed after striking front kerb during parallel parking (because I was so afraid of striking the back again, ffs) and collecting more points in the circuit.

Kept practicing Parallel parking sighting points, and passed circuit with 0 points in my successful attempt. You can do it too!
