Johnborrowman - Im sorry but unfortunately we cant tell you whether you have DID (MPD) or not...it is you that must tell us whether you have it or not..

you find out whether you have it or not by contacting your treatment providers (ie your medical doctor, your psychiatrist, your therapist....) your treatment providers will then refer you to a psychiatrist that does diagnostic testing for all medical and mental diseases/disorders that can possibly be causing your symptoms..for example you say you feel like you are someone else...well there are thousands of medical and mental health conditions that cause this same symptom. DID isnt the only medical/mental health problem with identity issues.. then your treatment providers will tell you whether you have DID or another problem that shares the same symptoms...

we cant diagnose you here but we are allowed to tell you what jumps out at us with in your posts...

one of the things that jumps out at me is that you said you dont have alters.. the very first diagnostic criteria for having DID is having alternate personalities that take control many many times, these alters have to be a special kind that have their own way of being, own way of thinking, and own way of interacting / pursuing their own life, goals,....

Another thing that jumps out at me is in another post you posted you dress and act like john borrowman... this alone doesnt say you have a mental disorder... in fact there are lots of people here in the USA that dress and act like their idols of music, acting dancing.... the biggies around the USA are Evis Presley, any Star Trek character/actor/actress, britney spears,...oh gosh I cant list all the different actors /actresses/ music idols being represented here where I live and work.

people do have their hobbies and idols they like to mimic/idolize/ pretend to be/...

for some people its called completely normal for others its called OCD for others its called Schizophrenia/ delusions/ manic.....

there is much more to being DID than choosing to act like / choosing to be your favorite actor/ actress/dancer/singer.....

My suggestion contact your treatment providers, they can work in depth with you on this and figure out why you need to be like the actor John Borrowman. They can test you for all the mental and physical health problems that this is for you.
