Issue with virtual copy edits writing to both the virtual copy and the original

Thank you to anyone who might be able to help.

I edited several images in Photoshop.  Once those edits were saved in Lightroom I made virtual copies of them so that I could make black and white versions.  I absentmindedly imported the originals into Photoshop, did the black and white edits,  and saved them.  The black and white edit wrote to both the original and the copy.  Is there any way to get the original color version back?
