I created a catalogue and lightroom CC closed down, when I opened it again my file panels and changes had gone. I tried to import my files from pictures again and found that my current processed information was missing
Re-Importing is mostly never a good idea.
You found yourself why, everything done before with an image is lost.
Changes made to images are immediately saved to the catalog. Maybe you opened/created a wrong/new catalog. Try to open catalogs found in File menu / Recent and see if one has your edits.
