Gordie, East, Jim, and Neffer, thanks for the additional feedback. It sounds like helping them get her a gift is the right thing to do. Neffer, I think a grim reaper costume might be more appropriate!
Yesterday I met with my IC. She said it sounds like I'm backsliding and becoming "wrapped up" in STBXW again. She's right - the OM stuff knocked me back and really stressed me out. It was like the standard effects of snooping, multiplied by 100. IC told me I need to focus on myself over the next month, in preparation for the mediation. Time to find some cheap GAL activities. The next 30 days - x-mas, STBXW moving out, custody and financial struggles, and mediation - will be really rough.
STBXW never came home last night. I texted her this morning to ask if she was still alive, and she said yes.
