brain damaged - no, literally

Sorry I haven't been online and keeping up with the flist. I've been catching up with a few long-lost friends and doing upkeep things in the real world. But fear not: my LiveJournal obsession is alive and healthy.
To save having to have this conversation with several people, I'm just putting it here. It's kind of embarrassing, but it needs doing. Questions are welcomed, but for once I am going to give the touchy-subject warning. For serious: no teasing me about this, or I will be interesting to you. In the Chinese fashion.
