DD was her high school sweetheart who'd had a nervous breakdown.

The vid is definitely on my list :) I saw a Buffy vid to the song that gave me the idea. Xander was who the DD character would be, Angel equated to Big, Riley was Aidan (HAH, you love that don't you?), Spike was the Russian. At the end it was sort of scenes of everyone, and I'd have scenes of Carrie and the girls ("loves of her life").
