Vent!
I'd cry! When I had to go back to work with my first I had about 100oz in the freezer. Everytime we left the house I was afraid that our power would go out and my milk would be ruined! We went on vacation right at the end of my maternity leave and I made my mom keep it all in her freezer to "babysit" my milk in case anything happened while we were gone. Good luck rebuilding the stock pile!
