Hi Sandy, and Welcome!
Sandy, I probably have some strangely comforting insight for you. Even when you lose the extra weight, you will still be the same person, and perhaps you will still feel like the chubby one in the group, I don't know. What I do know is losing the weight can be a time of transformation, so it is actually a good thing that it takes a while. We always have a lot of transforming to do.
Imagine a thinner you. How does she dress? What does she eat (try to be realistic, she is thin, and she is maintaining it)? What does she do for exercise? For fun? How does she talk to people? Did she take up horseback riding, or did she start working for Habitat for Humanity? How does she handle aversity? I think at the beginning of our journey, we don't know any of those things. We always have a lot to learn, strategies to try out, styles to try on.
I think the SparkPeople "FastBreak" is a great way to start too. Give it a try. Try what the website suggests in the emails. Let others on the site help too--join a challenge, for instance, when you feel stuck somehow :-)
Remember to reward yourself, with non-food rewards, for reaching your goals, and also just sticking to plan!
Some non-food rewards are, a day trip to a park or a beach, a manicure or pedicure, a hot bath with some wonderful bath salts, new shoes, craft supplies, exercise equipment or outfits, or whatever floats your boat :-)
