So, my question is this. Does this give them a permanent sense of satisfaction? Does, looking like a model help their opinion of themselves
I think once you understand the disorder, you will answer you own question. My ex, at 34, believed she was the hottest model on earth. I had to take pics of her, where ever we went. She even went so far as to book her own photo sessions for herself. These pics all get put onto her FB page so others can tell her how beautiful she is. She also has a website for her "model agency" and her own fashion blog. Mostly just pics of herself, and in 2 years the model agency never got any bookings.
Now in the real world, she is only a call centre operator. She never has had any stable job, prior to this one. Only been working about 2 years now.
So my answer to your question. They will do anything to get attention just to convince themselves that they really are the best thing since sliced bread.
