What. the. hell?

[hmpf]

I was looking for a comments discussion from around 2008 in my mail program just now, and was aghast to notice that ENTIRE YEARS are missing from some of my folders there! Among the things that are gone are all LJ comments from May 2006 through August 2009.

I am incredibly alarmed. It feels like a large chunk of my brain went missing. And I don't even know how long it's been missing.

I have no idea what happened.
