I failed my first road test with the DPS, really embarrassed

For anyone wondering, I am under 18 and have been driving with a permit for about 10 months. I took my road test today, and got perfect on parallel parking, but failed as I was going onto the feeder. I was really nervous because I had 2 examiners in the car, and the one in the front seat had a terrible attitude. She sighed when she got in my car and rolled her eyes after l asked how her day was so far. It definitely put me on edge and I could tell she was impatient. As I turn on to the feeder, I wait for the clear of ALL lanes before turning. Then, out of nowhere, a mustang speeds towards me (signal on) from an angle I couldn't see and proceeded to speed right in front of me as I was turning. I got an automatic fail and I feel really bad. My mom told me that my anxiety was probably because of the attitude of the examiner. The person was in the back and was understanding and told me to not be discouraged and how he understood I was nervous. He seemed to score the examiner in the front seat really bad, so I think he is kind of on my side. Overall, I am really embarrassed and have my next road test on friday.
