There's been some good advice on here already so I'm not going to repeat that but I do question your relationship with your instructor.
This phase of flight is some theory and the rest is almost all skill... skills are learned with demonstration, practise, feedback, coaching (which is about dialogue not JFDI), more practise and your FI should be doing all of the above.
I agree that "Fly the Plane" is not a good enough answer - so whilst you can get some good tips and advice on here you need to discuss this more fully... if the FI says "Don't worry about this for now" and advises that you should concentrate on something else instead then fine (in other words we'll sort this out later).. but you implied a "put up and shut up" type of answer and this won't do!
I'm sure that with persistence and practise/coaching you will be fine... we've all been there at some stage - it can be very frustrating when you seem to go 'backwards' but that is all about learning new skills and is part of the deal. Have a look at

Good luck and let us know when you can land on a pinpoint
