if this was me the first thing I would do is ask my therapist questions like...

what do you mean by Dissociative Disorder NOS?

reason I would ask that question is because no where in the whole world is there a dissociative disorder called Dissociative Disorder NOS. The American Psychiatric Association made changes to the american mental health system including throwing out all NOS labeled disorders and adding to other existing disorders and making new dissociative disorders.. here is a list of dissociative disorders america has.

(the two general dissociation disorders are now called OSDD and UDD, UDD is used for emergency situations and gets changed OSDD has many different things in it, each has their own names but are not listed here, none are called DDNOS. they are names like macropsia, tachypsychia and other strange and long names. your therapist will have to tell you what that strange name is if they diagnose you with OSDD, its the rules for being diagnosed OSDD.)

I would ask the therapist to see their DSM 5 and ask them to show me what they mean by Dissociative Disorder NOS. after you know exactly what your therapist meant things wont be so confusing or scary anymore.

another thing I can tell you is that one thing that helped me with getting diagnosed was that my treatment providers told me nothing changes, I just now have a name for what has been happening all my life . the only thing thats going to change was my learning better coping tools and healing so that I no longer have the problems I have had all my life.

I am now an integrated person meaning all my alters have joined together with me to form one whole person again instead of alters.
