It's such a shame that you can't rely on your L exactly when you need her the most. Have you consulted with any others? I think I probably would have done that - interviewed with at least two others to get their take on it.
And although I understand you can't go into detail, I hope it's only about stuff. Stuff and money - and you being very successful - can always be replaced. The older I get, the more detached from money and things I become. It's partly from having been robbed a few times, had hassles with long-term storage (and realize that you really don't need all of it) and lost most everything else in a natural disaster. Nothing is really secure, except this moment today.
I hope it gets all sorted out.
