I was going to post those exact two! Weekes' and Ellis have helped me tremendously.
One of the most beneficial skills learned from Weekes has been the ability to let a period of increased anxiety run its course without attempting to fight or avoid it. To feel all of the changes (blushing, breathing changes, racing thoughts) and not be impressed by them. Just accept them as sort of an overgrown reflex and move on.
The chapter on "Feelings of Unreality" is eerie because its so accurate in its description. Also to see something in print (not on the internet) describing DP is uncanny.
Do you practice some of her techniques? Floating, etc?
