indeed the syndrome can take on a life of its own (become part of their identity), and perhaps that's when it's at its most fragile. it's why after 10 years of suffering your pain could vanish immediately after learning it may serve a psychological purpose.

but i think for many neurotic people (and most of us are indeed neurotic) the syndrome (i use lacan's jouissance) serves its purpose just fine. so don't you dare take it from them.
