I know the feels.... I had 120+ pages of a 10 series book I was writing + the entire timeline planned down to the day utterly destroyed because my old laptop would start melting if I left it on for more than a few min. The timeline itself was something like 80 pages and had every chapter planned out.... when I lost all that it was the only time in my life I felt truly suicidal.
I think I wouldn't leave my bed for at least two weeks if someone stole my sketchbooks
