What do i do in this situation?

Im a 22 year old male and i am learning to drive. I've had about 5 or 6 real lessons in all and i really felt confident in getting my license. When i took the first test i flunked because my turns were too wide and sometimes i would swerve in the other lane. the second test i wasnt confident at all because i was so hurt from failing the first time. i kept hesitating and kept grippin the steering wheel hard out of nervousness. failed that one too. do i need to keep practicing and if so on what?
