An awful experience

I moved recently. So I went to the closest grocery store. I'm not very familiar with the area. I wanted to get some food at the restaurant up the street. But I missed the turn. I thought i could make a left and turn around. I accidentally turned left into oncoming traffic. By some miracle, I managed to get back into the parking lot and turn around without cops. I am relieved to be OK and that I didn't hurt anyone. But I'm terrified to go back now. I'm still pretty shaken up.
