My first solo - and the worst flight of my life

Since the senior instructor seems to have a good opinion of you,
perhaps you should sit down with him/her, explain the situation --
that your current CFI does not understand your mode of learning,
and that you'd like another CFI.

If that doesn't work, is there another school anywhere close?

Learning to fly is frustrating at times, but at no time should
it be harassment or make you unhappy.
