Should I repeat road test tomorrow? Opinions please?

I am 31, a bit old to take driver test, I did well days before test driving on highway, city etc. Today I failed the 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 I 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 taught 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. But I need to drive, I will be moving next week i the country and while hubby at work will be alone, you never know
