I was the same. However you will get used to it and slowly the more lessons you take the more confident you get. Now I can switch gears, break, turn, indicate, wash the wind screen all together with my eyes closed LMAO.
At first it’s very scary and seems like quite a task. So I totally understand.
But slowly you will become more and more confident.
Your very new to driving and considering you have only done 4 hours worth of driving, you do need some more practice. and remember a normal person to required around 47 lessons before they can take a test.
So don’t worry, keep training. Maybe practice on someones car, when I was learning I practiced on my mums car in Morrison’s car park. You can also get a learners insurance which is not too bad if you want to take someone car on the road. Obviously they would need to be sat next to you at all times.
