Ooooh, I think your file is lost. You're out of luck
I use an olde5 version of photoshop with imageready for animation, and if you open it in imageready it 'closes' it in photoshop and your work will be lost if you don't transfer it back before you save, or save through imageready.
Ah that must suck, I'm sorry to hear that. I'm not expert at this but I hope somebody will get you an answer. Just don't work on photoshop when your charger is not plugged because I think photoshop takes up too much memory that will make your battery drain faster, I'm not 100% sure about this but that's what I experienced from working a lot with photoshop.
