Lost photos due to unintended mouse selection in Lightroom

Hello everyone, I was in Lightroom editing some photos, when suddenly the mouse started selecting several things at the same time, and in the meantime I left Lightroom, went to the Finder and suddenly selected several photos and deleted or moved them them. I can't find these photos anywhere. After this happened, I didn't delete anything that was in the trash and still, the photos aren't there. It should be noted that I am not using the Apple mouse.

Photos are very important to me.
