if you read past posts by members here in psych central you will find that each member has their own reasons why they are researching various mental disorders and feel that they may fit in with this or that disorder.

let me give you an example of something say you never knew a cough was a cough and what kind of cough it was, how would you tell your doctors that you have a special kind of cough without having the right words for it that a doctor would be able to understand.... you would go on medmd website and research all the different coughs then go to your doctors and tell them you have a dry hacking cough not a wet, deep cough. with those words a doctor can say ok this cough is a cold not a cough from smoking cigarettes.

my point many people research and look for dissociative disorders because it gives them a way to talk with their treatment providers, others dont have treatment providers so they have to research and narrow things down. also if someone say has one disorder vs another well that makes them feel less confused and the treatments are different they know what they need to do for that problem if they such and such of a problem.
