YAY - you checked in!
Sounds like DS is doing wonderfully & AW is continuing her progression..... how bittersweet. The best part here though is you getting comfortable with detachment & not getting enmeshed in her consequences... that's got to feel good!
I also use the daylight bulbs in my office & love the salt lamps I've added both there & at home. I bought them after having such great experiences in local salt "caves". If you've got something like that around they can be surprisingly helpful. (anything generating negative ions will likely be soothing)
'course, you can all just hop on the Codie Bus & head on down to FL for some sunshine & beach time over the winter too. (I'm semi joking but for reals - a sunshiny-tropical vacation over winter isn't a bad idea if you suffer from SAD)
