Alright full head brah. You haven't specified exactly what you're struggling with? Sounds like you passed the theoretical part but the practical one is the issue? What have you failed on so far with the driving? If it's something different each time it could just be nerves. Find out what the weak spots are and keep on practising.
I know of various people who struggled with driving regardless of their academic/intellectual prowess. There's no correlation at all so the people laying into you are dumb. I know a well to do banker and several medics who can't drive despite trying loads. Yet there are people who are not too bright and can drive well. One passed in the end but he still doesn't "really drive" and it's obvious to all, so I don't include him. You can't rely on him for lifts through town, road trips and taking turns on the motorway. He'll often say no, but it's a good thing as he's not safe. And accidents can really bump up your insurance in the UK. When you see him drive, I feel like he's a noob and you have to watch for him and can't switch off.
I find driving to be calming, forever on a never ending scenic route with close friends and ambient music. No accident yet touchwood, though it's sometimes out of our control. I love driving and cars - passed first pop at 18. My tip would be the same with any challenge even though this one was natural to me:
know your subject and practice. Be organised in some way (in your mind in this case), that will calm you when it comes to test time, look forward to and love what you're doing. In this case, the independence a car will give you should be a motivator since a car is not a hobby for you. How to get organised? Sit with people who actually drive well and try to second guess what they'll do and how they're doing it while keeping full road awareness. I remember watching my Dad as a young child in the front seat and knowing what he is doing and wanting to do it. Far too many people fail due to nerves or being ultra careful which leads to mistakes.
You have all the technology and books now. Watch some youtube videos on people failing and passing, but really focus and imagine it's your test and you're in the seat. There are simulation centres in the UK too where you have to avoid dangers on the road. Not sure how useful this is but it gets you thinking. Make driving your life and practise as often as you can. Remember actual drivers drive different to "test conditions" such as both hands on steering and checking the mirror regularly e.t.c. So you need to know the "correct test way" and make it a habit. If you're struggling with parking, since I presume you know what car you will do the test in, there are markings you can place in the rear window corners so you know when to reverse and lock the steering. Or for example to park into a bay, you can do it according to the position of your wing mirror. Look up tips for this because there are many and I have no idea. Know your test area so you don't break the speed limit on streets when the time comes and get used to smooth gear changes with the vehicle.
You can do it with dedication. Maybe change your instructor if he sucks.
It's all in the eyes, vision of a better future and a window to the interior.
Thug life, no eyes.
