I think she hate John and the little people he is so intouch with. http://www.freerepublic.com/focus/f-backroom/1163131/posts?page=11608#11608
I was speculating early last month that she might have a pill problem. Then I saw her at the DNC acting a TAD overmedicated. THEN I discovered she was proscribed Prozac to treat depression after Heinz' death....not surprising, but if you put all the pieces together, it's looking like she's been pill dependent for years. Oh, and Teresa describes herself as "needy." All the ingredients of an addictive personality are there, including her and John's weird, co-dependant relationship.
