My save file... (Patreon)

Thing is I have just got blackout while i was drawing then after that my psd files turned out like this. 

I am in very near to finish this week illustration and this happened...  If anyone know how to recover or fix corrupted PSD please help me.  Worst case that we don't have anything in this week and i have draw it from beginning....  

I will try my best to finish January batch before 15th Feb... This gonna be hard for me....
