So, JB was "more interested in cleaning the empty refrigerator twice a day" than feeding her daughter -- that's how bad her OCD was. FYI, OCD is an anxiety disorder and it sounds like hers was really unchecked. OCD compulsions (i.e. behaviors and thoughts) get worse in times of increased stress. Sounds like this divorce has been highly stressful. When OCD compulsions get to the point that they're interfering enough in your life that you're not tending to your kids' basic needs, that's a train that has run pretty far off the rails. (I'm a mental health therapist, btw).
Also, SM has made some pretty weird statements to the news -- he's kind of a creepy-sounding guy. But, at least he's made statements to the news (both addressing JB and the possible kidnapper/s). Why hasn't JB made a statement? From her POV, there are only 2 possibilities -- Sky walked off or Sky was kidnapped. Why isn't she appealing for his safe return?
