I just went back and read your past posts and discovered you posted about this before. in the past posts you stated that you are 17 and sometimes you willfully create persona's that you act out\pretend to be... and you wanted to know whether this is a mental disorder...

theres a difference between dissociative type alters and a person purposely creating persona's to be because they dont want to be their selves.

a person creates persona's (pretending to be what and who they are not) for many reasons, some of those is because they want people to like them, or because they are in a school play and are acting a part,

dissociative type alters are not like that. there is even a diagnostic criteria that says this kind of alters can not be because of fantasy play (in other words they cant be because someone is slipping into these voluntarily created persona's to play pretend that they are something or some else.)

if you were here in my location what you are doing would be called many things like you would be called a great actor and should be in plays, musicals, and such like your favorite tv persona's (actors and actresses) in some ways what you are doing in my location would be called behavior problem not a mental disorder because its in your control to pretend to be other people.

but the short line is because of the diagnostic criteria saying the problems can not be because of fantasy play you would not be diagnosed with any dissociative disorders that have alternate personalities.

that said we can not diagnose you so please dont take my explaining how things are in my location as making a diagnosis of you.

you are 17 years old and I can understand how and why a 17 yr old wants to remake their self into other people but thats not a mental disorder per se,

my suggestion is if you feel you are having a problem with your purposely creating these persona's when you dont want to be you, contact a treatment provider who can help you to use this is positive ways that can teach you how to not create persona's when its not appropriate for you to do so and to pretend to be someone else when it is appropriate like maybe join your high school chorus or a near by acting class.
