Extremely embarrassing situation?

Heyy,

I'll be 16 soon and am currently working on my L17 and A1 driver's licenses. Something very embarrassing happened to me today. I don't want to go back to driving school.

I was parked on my moped in the school parking lot and was just about to leave. I looked left and right, didn't see any cars (I was very tired, rolling along at 20 km/h), and wanted to turn left. Out of nowhere, a car came from the right, which had to slam on its brakes, and I had to swerve into the other lane. So, I was almost run over right next to the driving school.

I think both of my two driving instructors saw it. One was in the parking lot with a L17 student in a car that was also about to leave. My A1 instructor was standing outside right in front of her. It's possible both of them, just one of them, or neither of them saw it.

My A1 instructor said that if you don't open your eyes, you can just get off the motorcycle/moped and go home. I'm so embarrassed, what should I do?
