I know what you mean, it is so hard to be on a weight loss journey when it seems like you are a lone traveler. Here on Spark people many of us are the feeling the same. I find that blogging is a great way to let out some frustration as well as announcing to others what your goals are and your progress as you work toward those goals.
Stay focused on what you have accomplished rather than on the areas you failed. If you do fall short, acknowledge it and then at that moment move forward with a new goal.
Best wishes to you and I hope your journey is successful.
