Sounds like you might benefit from taking a break from circuits. Ask your instructor to move onto navigation for a lesson or two.
Absolutely NOT!! All that would do would be to ensure that the spectre of circuits and landings was still lurking in the back of your mind, resulting in your not concentrating on anything else properly.
Don't run away from your present situation - face up to it and conquer it!
Find an instructor who can teach 'point and power'. It is a far more natural way of flying the approach and landing and is also the method which the RAF use.
