As others have said, it's all about practice. With time (changing from someone to another) it'll become natural and you won't even think about what you're doing.
One important thing is not to get caught in some bad habits that will be hard to shake later on, namely your hands positioning on the wheel, driving with one hand on the stick, having your foot resting on the clutch at all times and so on.
I've started driving when I was 12 (so, 21 years ago) in my father's FIAT 127 which I miss dearly, and when I went to my 1st driving lesson, at the legal age of 18, I was already pretty comfortable with all aspects of driving, aiding to the fact that the driving school car was a Corsa Mk1 1.5D, easiest thing to drive EVAR.
Plus, even in my case, it was easy to get frustrated by driving lessons, because you aren't driving a car to where you want to, or to get anywhere.
In your case, it's learning how to maneouver a car in every aspect, and learning how to reverse park, etc., which adds to the frustration you're naturally feeling.
Just stay focused on doing everything well, and then when you have your permit in your hands, then you will actually
drive. Right now you're learning, that's all you're doing. It's not supposed to be fun anyway.
Don't stress about it much, "just do it".
