Continuity
Early flying training needs continuity,but unfortunately this is increasingly difficult as the clubs/schools struggle to keep instructors as commercial jobs become available.
You may want to take a break and find an operation THAT SUITS YOU (after all you are the customer)
Better to do this than feel unhappy about the present situation which will certainly NOT BE CONDUCIVE to what should be a pleasant useful learning experience.
Multiple instructors at the early PPL stage are not the way to go.
Confidence should BUILD as you progress and in such a way that you feel more comfortable with decisions and actions you take. Good Luck
