theres nothing wrong with wanting to be more like the person you want to be, whether you see it in other people or not... in my opinion..

when it starts causing issues though thats when we need to do something about it, when it becomes disorder...

i only mentioned borderline because with that there is identity disturbance, and maybe can take on traits of people you are around because lack of identity... changing from one way to another according to groups of people you are around, or persons..?

i see things in other people that i cant stand and i also see things in people that i adore and want to be more like, as well as want to be less like... and i think thats normal

if its causing problem i think it couldnt hurt to talk to a therapist about, therapy can be helpful anyway you know, for many things maybe even we arent aware of

dissociation is "separation of normally related mental processes, resulting in one group functioning independently from the rest, leading in extreme cases to disorders such as multiple personality."
such as normally integrated memories, feelings, thoughts... ?

disassociation is more like a conscious choice to disassociate from something.. rather disociation is more of unconscious... if im not mistaken... 1 you choose the other you dont really choose... hence the triggers causing reactions rather than mental conscious choice about something...

identity disturbance maybe something you would be interested in researching?
