Watching her resignation speech, I had the feeling that Sarah Palin is struggling with anxiety issues, and feels like she may be coming apart.
She has shown in the past year a proclivity for stepping on the gas and pushing it all the way down. This is consistent with an anxious personality. We all know such people. They may be perfectly nice people, but they are fundamentally "uncool" people -- thin-skinned, unable to let things go.
I know a lot about this from my own experience and that of family members.
I am against Sarah Palin politically, but I look at her today and see someone who knows she has drifted into the deep end of the pool, and it is a place she does not belong.
I expect her to seek seclusion and very controlled public situations. Heck, she has been doing that all along.
