Its a tough place to be if W is indeed clinically depressed...my W is and has been since her teens...her meds were too high and she was very flat, ever since I knew her...now she's off her meds...
The difficulty is like you said, her possibly bouting w/ depression, withdrawal from Om, and typical WAW mentality...UGH!!
There is no real way to advise her to seek help for the depression...like Allen said, you MUST set the example of seeking IC/ FT and hopefully she will follow suit...maybe then she can address some of the depression.
I also agree, you mention alot about W sleeping- huge sign!
As for W's tests (and thats all they are) reg "oh lets get this...no wait I wont be here..."
Just cattiness and cruel- MEANT to get a rise out of you...so you can either be an ass or be a wimp and start begging...push-pull
You seem to handle it well, I give you credit. I wasnt at these boards when all that was going down in my own sitch...
I really think you're doing a great job and you're articulating and analyzing your behaviors very well
