File this one under revisionist history. I have been noticing this for a while but I guess it is so obvious that no one has mentioned it.
Her standard story which has been oft repeated is that she was thin until she went to college and then PCOS caused the enormous weight gain. And while there are two pictures of her at her most slender most of the other ones to not bear that out. She is not thin (not obese but not thin) in her prom gown which I assume was shortly before she went to college. She looks squeezed into that gown and spanxed from neck to knee. I maintain that she has always struggled with her weight and depression. Her eating disorders seem to have ranged from bulimia to a period of anorexia to uncontrolled overeating.
And, I'm going way out on a limb here, but, hey, I'm not a psychologist but I am in my arm chair so here goes. Her appetites (food, alcohol, sex and attention) are an attempt to fill something that is missing. And having a legion of leg humpers seems to be what she thinks she needs although it won't be sustaining and when her show and speaking engagements dry up she will be in worse shape emotionally.
I wish she would do a lot of things but a pet peeve of mine is that she intersperses her current photos with those taken when she was much younger. The reason it bugs is that her acolytes don't realize that and gush at how beautiful she is which only serves to feed her ego which makes her continue.
