A sad story.
Idiot instructors who shout at their students are despicable. I once had a poor instructor who shouted at me right in the middle of me flying a go-around, in a twin piston, at night. I immediately shouted back, telling him not to shout at me and that I was cancelling the test and would be changing instructor. Another time, I sat in the back while my colleague on the course did a flight with another instructor who was very rude and shouty. I witnessed yet another instructor telling off a foreign airforce cadet for going into town; “who gave you permission to go into town?”.
YOU, or your family, are paying these instructor’s wages. They are working for you. There is no reason to be rude or shout at a student*. If something is going badly wrong, a calm, authoritative “I have control” from the instructor is all that is required.
If a student is not “getting it”, then the instructor is at fault for either not explaining it properly, or not realising that the student is not ready, or that the student does not have enough skill.
In the OPs case, I think you must ask yourself a difficult question: Do you really want to become a pilot? If not, you must stop now, and stop wasting your family’s money. You will have to explain to them and others why you didn’t become a pilot, but there need be no shame or loss of face. You just need to find a way to reconcile it to yourself and others. At least you have tried hard, but it is not for you.
Good luck.
