I lost all my iMovie projects because I accidentally threw iMovie library in the trash and revived it by moving it to it's original folder.

Hello.

I lost my iMovie projects because I accidentally threw the iMovie Library in the trash and immediately but it back to it's original folder. As I did it, I lost a tremendous amount of storage and the 164GB of space it took, reduced to 31GB of space that application used up. Is there any way I can get this back? I am freaking out and am really nervous. I have made so many things on iMovie and was about to upload a project.
