[Mac] Psd file corrupt, please help!!

i working on sample info-graphic twitter put in portfolio, working fine. copy-pasted .png google images project , got screwed up.

 

the whole picture started flickering in squares , parts turned yellow. saved , quit, assuming graphical glitch fixed restarting application, didn't work.

when re-opened file layers wiped clean, , had nothing on them, , still yellow.

 

i tried drag still healthy layers new project save work, wouldn't let me.

then tried copy , paste layers new project, , worked, appeared in greyscale.

my final effort recover hour of work save corrupted file .png , .jpg files, , try drag them onto new project, both appeared in black , white.

 

has else experienced this? can recover work?

do have time machine turned on? keeps hourly copies of files.
