Whoa B,
I hope today is better fot you. I know how you're feeling. When I moved from my last apartment into our first house I too lost 90% of my vinyl to an undetected slow leak from the owner's kitchen above our apartment. The covers had been soaking up the water for a right long while. We only noticed it when a friend attempted to pack 'em up and they proceeded to fall apart, I mean they were really, really wet. And they were lined up along the wall in the living room, they acted just like a sponge and we never noticed it... This too shall pass
