Too nervous during road test to get license, should I give up or re-test tomorrow?

I am 31 and was doing fine yesterday, I did three point turn well after an hour of practice, I have drove on highways and city in these past two months on weekends. But today I failed road test, I started three point turn and hit the accelarator instead of brake and hit the cone and was failed at once. I have never done that before! and then once home when parking I did it again! I went over the curb because hit accelarator again, I was still nervous and thinking of what had happened on the road test. What can I DO? The tester said I do not drive safe and need more practice, that usually they suggest 5 months of practice but I need my license now,my hubby which has been teaching me is afraid to drive with me now, there are no instructors in my area and I am new no friends or neighbors, I am thinking to just let it go, nervousness and driving cannot go together, I have always been a nervous person for minor things and it is my nature. Any hints, or people in my situation which can help?
