Need help reversing processed clips please

Hi, I'm new to this and got myself in a pickle while putting together a video. 

i attempted to create a multi-camera sequence by trying to merge two clips from cameras that were running from different angles. 

Instead of creating a multi-camera sequence i ended up with folder called processed clips in a bin called processed clips. The two clips I attempted to link together are in here, separately and I am somehow missing about 30 other clips from the bin. 

i attempted to re-import my missing clips, but have no idea where they ended up, I can't find locate them. 

Is it possible to reverse processed clips somehow and get back to a place where I can start over on trying to create the multi-cam sequence? I'd hate to lose so much work, but at this point I think my only option might be to start the whole project over?

 Thank you for any help you can provide me with. Happy new year.
