Help connecting missing linked photoshop files back to lightroom

Hello

Lightroom Newbie here. I am freaking out a bit lol. 

I had linked my Lightroom files with photoshop files and was editing between the two programs. 

I moved the folder that my photos were on by accident.  Now all my files are missing.  

I am trying to link my Lightroom photos back with the photoshop files but can't find the photoshop files (I thought they were stored in Lightroom??)   Now I have lost all my 50 hours of work. 

Please help

Mia
