Munchausen's syndrome

After trying to produce and image for today's photography lesson, I realised I would need to do a LOT more research, which would mean narrowing down my idea.
Browsing through the internet for different mental health issues, I discovered Munchausen's syndrome, where people cause their own symptoms, and have them checked by different hospitals, waisting their time. They often have an extensive medical knowledge, and so the symptoms need to be checked thoroughly, waisting medical time.
I think depression, eating disorders, and schizophrenia also have potential to make interesting photographs. Synesthesia would also be an interesting area to look into further.
