A lot of people think that when they reach their goal weight/maintenance, that the journey will become easier or even end. That could not be more far from the truth. Maintenance, for many people, is a lot harder than losing weight. When you are losing weight, you see maintenance as the light at the end of the tunnel where your problems will be solved, yet it isn't. It is a romanticized vacation that is still GOOD, but it isn't quite what you expected. Yes, there is sun and sand, but there is still early morning wake ups, checking in at the desk, dragging your luggage around ~ all things you didn't plan for when you envisioned your wonderful destination
Self-esteem issues is some of that baggage. We think that when we are slim and healthy, that we will no longer be self-conscious of our bodies and no longer need to worry about what others think. As you've discovered, it's not true!
