Hey, Nil Flaps, glad you feel confident enough to share your thoughts with us other mere mortals. We make clangers too. And will continue to. Unfortunately, it is part of being human.
Your instructor obviously knows your potential capabilities. Otherwise, he (she?) would have insisted on coming with you. And he is wise enough to advise you to have a few days off before you continue.
Nothing I read in your post indicates to me that you are a fool. Going to discuss the events with your instructor was anything but foolish.
Oh, and don't dwell on feeling embarrassed. Put it in your little book of lessons entitled 'I learn't about flying today from that'.
Don't beat yourself up, and look forward to your next session of aviating.
