I wasn't exactly scared about reaching goal, but I was very worried about being able to keep the weight off once I got there. By the time I was closing in on goal, I was a pro at weight loss but was concerned that I didn't have a clue about maintenance. Who ever talks or writes about maintenance?
What I quickly discovered was that maintenance looks just like losing. I reached goal - hooray
- and got up the next morning, ate the same breakfast, and went to the gym as usual. It was quite anti-climatic! It wasn't like all of a sudden there was a shift in how I was eating and exercising. In reality, nothing changed.
Do you think that you might be scared of goal because, as you say, you see it as the end of the journey? And perhaps the next part - maintenance - is a big unknown to you? Honestly, goal isn't an end at all; it's more like the conclusion of Chapter One in a book -- the other chapters are all the many years left in your life. It's really just one big journey that has no destination and no end.
Since you obviously know how to lose weight successfully, you'll be just fine once you reach goal if you just keep on doing what you're already doing so well.
