My prayers are certainly with your family and especially your daughter coolx.

Today I pulled the weather stripping from the bottom of my doors to check for rust. It's not rust free but it looks pretty good, the passenger side has a little bit right in the middle of the door. The drivers side had the worst spot with some flaking at the door jam side right were it curves around the bottom. Cleaned both sides really well and scrapped the worst off, then I applied two coats of 3m rust converter, after everything was dry I masked the area and sprayed a good coat of spray bedliner all along the bottom of both doors. I will keep an eye on it, hopefully it does the trick.
