These pictures are disturbing on so many levels. It's not just the awkward angles and sucking in her gut, it's more than that. I think she did the classic "shrink the picture ratio horizontally to make yourself look skinnier" trick which would account for how strange her head looks in proportion to the rest of her body. At least, I hope she did that, because if not then the weird proportions could indicate the onset of an eating disorder. I don't want to armchair diagnose here, but the rapid, extreme weight loss and constant obsession over food and her weight are enough warning signs that - if Pixy were a relative or friend - I'd consult with a doctor about it.
