Hi!
Don't worry, just be positive...you will pass! I suggest you read this http://www.2passforum.co.uk/ to help you with your practical test.
I passed mine 2nd time however I've been driving in Manila since I was 18 so that gave me the edge. I remember my 1st examiner was a lovely lady, I was relaxed during the test but she failed me for being in a wrong lane in a roundabout. My 2nd examiner was a grumpy old man, I couldnt even open the car door! I can see he was getting impatient bec I pressed the key several times and yet doors were still locked. He said are you sure you're pressing the right one?! I can see my instructor running towards us then I just realized I was pressing the 'lock' key. We got in eventually but I was already shaking like a leaf, from the examiners tone he wasnt happy. In the end, to my surprised he passed me.
Good luck!
