Probably no way to restore your edit but it does depend on how you edited and how you saved or exported the image.
A Gimp Save keeps layers and certain data, but might not survive (say) a crop.
An export is different again. It can depend on the export format. This is why a screenshot of the full Gimp interface, showing layers / tools / tool options together with details of your workflow might get you an answer.
Examples shown inset as they appear in Gimp: Left is a tiff that keeps the area outside the canvas. Right a PDF that ignores the visibility of the bottom layer. From your description it might be PDF.
