I think that fear is so understandable and so common. Remember the recent thread about being afraid to get to goal (was that here or in Supprt?)? I think losing weight is a scary proposition. It does change our lives and that can be scary. It also carries with it the weight, if you will, of accountability. And the pain of unsupportive people who will be waiting for us to gain our weight back. Finally, there is the disquieting reality that with weight loss will come life changes that might not feel comfortable. It is very similar to the couple with one alcoholic member who gets sober. Often times, the sobriety leads to divorce because the comfort of consistency is destroyed. Even though we do not enjoy being overweight, it IS comfortable. It is what we know. It is what other people know of us and, unfortunately, in some cases, it is why some people "love" us (the sister-in-law, for example, who is thrilled not to be the only chubby person in the family; the mother who feels loved by her son's lust for her food). To add a public declaration of one's weight loss success adds the extra pressure of fame, no matter how large or small) to the mix. All of this is extra pressure in this journey.
That said, you both seem to be handling it beautifully, with such grace and humor. You are already overcoming so many weight loss obstacles (Howie's back, for one) and you are still succeeding. Even with this plateau (which seems to be en vogue for this group right now, myself included), you have accomplished so much this far. Were you to stop losing now, your story would still be one of success and inspiration. I personally do not believe you will stop, though, because you have such a strong drive, a persistent attitude, a healthy plan, innumerable support, and a spirit that exudes happiness.
Plus you might get to keep the clothes.
