We all carry baggage that led us to make the bad decision to overeat. While it's harder to resolve the problems that held us down, we must forgive ourselves for using food as an emotional bandage. Forgiving yourself means accepting your past and accepting you will make mistakes in the future.
The best thing to sustain this secret is to keep your heart open. Open to others as well as yourself. There's no shame in asking for help and support. Always do your best and stick to whatever works best for you!
