Water leak and damage

I am flaming pissed off. I went to the storage unit we rent to get out my box of boots, hats, belts, buckles, etc for my move back home to Texas. The ceiling was buckled but repaired on the outside and the container with everything in it was filled with water, the lid was cracked because water had frozen. My deceased boyfriend’s buckles and boots and hat were in that box along with the clothes I had on when he had his accident. Just a lot of memories of when I had no fear, riding, I could still take care of animals and acreage. I lifted up one of my saddle blankets and the family hand down saddle had been exposed to water. The saddle is over 75 years old. My grandma and great aunt used it along with my dad and his siblings and then me. I tore into the rental office with the water filled container and saddle and wanted answers. They just looked at me as I stood there with tears running down my face because memories were ruined and I don’t know what I can salvage and what I can’t. The family ranch branding iron and other stuff from my great grandparents ranch weren’t too bad looking. I still can’t put words together to express how pissed off I am.
