HELP! NOTE DELETED EVERY SINGLE IMAGE!!!

I have an exam on monday and have been working in a note document for an entire week creating a study guide/exam review. My app just crashed and EVERY SINGLE PICTURE in the entire 23 page note (over 10 pictures per page) is gone. I don't know what to do. I tried going to the cloud version and all the images are gone on there too. HELP! i have a huge exam and need those images to study for it. what do i do to get them back?????? I'm freaking out and about to have a full blown mental breakdown
