I need friends to help me through to the end!!

Options
I desperately need some motivation. I am dedicated to my weight loss, I have lost 32 kilos so far (Approx 70 pounds) and I have about 10kg to go. I want to do this by the 5th of December 2014. I think it is 100% doable. I eat 1200 calories per day and work out every work lunchbreak to the tune of about 600 calories. Weekend I am a little more lenient on food, but nothing crazy nonetheless. I know it's possible, but I can't get rid of the doubt! Help?
