To confirm: you cropped, then saved, then closed, and when you reopened you only had the cropped version? If you hadn't closed, you could step back in History, but once you save and close, that's what you have now.
There is one thing to check: was "Delete Pixels" on or off in the options bar for the Crop tool when you did the cropping?
We learn by making mistakes. Save version of your projects in the future , also avoid shooting yourself in the foot. If you do though you have a backup with versions you don't have to start from scratch.
