7th week; I am in it on my own

This week I was very motivated to continue doing my diet. I won the biggest loser contest last week against my co-workers. Throughout the week, I was doing my diet and following strictly a 1500 based calorie diet. I was working hard, and was psyched about my weigh in on Friday. I think I enjoy losing the weight and getting a reward for losing weight. I usually spend the money on a reward I enjoy like getting my nails done or my eyebrows. Well, it did not work out like that. It was one of my co-workers birthday, so my co-workers which I am doing the contest with decide amongst themselves that they would skip the weigh in because everyone was going to munch out. I thought it was unfair and no informed me about this until I asked on Friday about our weigh in. I care more about losing weight than the money or winning the contest in the end. It is much more to me than that. I really depended on my co-workers as motivation and inspiration to lose weight. I thought if we worked together as a team, we could help each other stay on task and not want to munch out. I seem to be the only one taking it serious, so starting next week I am going to be doing this on my own. I have the self determination and will power to succeed on my own!
