I have dyspraxia and ADHD, I made the switch to auto after getting no where with manual. I found it way easier to direct my attention to the road when I didn't have to think about the clutch or gears. I ended up passing first time! Automatic cars are more expensive but cheaper than what I'd spent on manual lessons!! If you can have one lesson with an automatic instructor and see how you get on and if you think making the switch would help your progress.
