Seriously though , and in the words of Yoda " When you have as much immediate sadness and heartbreak in your life not hundred percent fully you will look hmmmm " .
In other words she`s recently lost her mother and her father ain`t been that there helpful in aiding the grieving process you know , plus she`s getting ever more deeply involved in third world projects etc etc which has to crank up the stress levels no end ! .
Personally i think there`s nothing actually different about her, apart from the physical fragility due to the weight loss. Something that she`ll hopefully work through
