I can tell you from personal experience, that a flood will eff your life. I had a business that was flooded out, 35 days after I had sunk $200K and way too much work into it, and the only things I was able to salvage were two plastic Rubbermaid trash containers. They were my $100K trash containers.
Yes, it is terrible. We left our home to escape a fire with just what we could carry in two vehicles. Leaving all the possessions you have worked for and not expecting to see them again is a whack. The house was spared. The second one in the second fire ten years later, the home place, was not spared. We lost the lifetime collection of a family in that one. We all survived, we all recovered but it was like a death in the family. None of it will likely lead to a shortening of my life though. What you can’t cope with you must endure.
That’s terrible. What state were you in?
