Images in Media Library Missing

I downloaded a plugin called Search and Replace to change file paths from https://myolddomain.com to https://www.mynewdomain.com within my database. No, I’m dumb. I did not back up my database.

One minute all of my images in Media Library were there and after using this plugin, they were gone!

Actually, they’re all there when you try to edit the image in Media Library, they just don’t show up in the library or on the visual side of the site. They also can’t be seen on the website lindseystirling.com. Lots of broken links because of it ??

I deactivated all plugins. No help. Changed theme back to twentytwelve. No help. Tried using the find and replace plugin to revert the process (i.e. Find: https://www.mynewdomain.com and replacing with https://myolddomain.com). Tried changing permalinks to default and back. No help. Again, I don’t have a backup.

Essentially, I need to know why even though my image urls in my database are correct, no images are showing in my media library or site itself.

Can someone please tell me how to fix this?
