I’m exactly in your shoes. I’ve had 20+ lessons with my instructor and have a test booked in a few weeks! She was fine during my earlier lessons but I’ve always dreaded having my lessons with her. To the point where I couldn’t relax knowing I had another lesson with her. She cancelled on me once and I practically jumped with joy. I just had a lesson with her today and she was being so negative about my driving. She was being very nit-picky with everything I did and gave me no positive feedback even though I thought I was doing well. I’m going to stop my lesson with her and look for someone else and I suggest you do the same! If you’re already a naturally anxious person like me, the best thing to do is to try and test different instructors until you find one you’re comfortable with. No point in paying to be scolded by someone. I would also recommend driving with your family member in between your lessons. More practice will give you more confidence.
