Crashes causing custom shape loss

PS has been crashing almost daily. I am getting very behind on the work I have due. I have searched for solutions, installed, reinstalled, and followed every fix solution i can think of. I have sent 20 crash reports just in the past 2 weeks. 

The worst part is that sometimes I can recover, but some of the crashes cause me to lose all the custom shapes I have spent the past 2 weeks creating. I have no idea how to recover or assure that they are getting saved so that I can attempt to retrieve my work. This particular crash led me to lose 10 custom shapes!! This is so bad. Any suggestions? Is there any hope of recovering my custom shapes?
