socially sensitive or disingenuous ?

recently i read life ceremony by sayaka murata, a short story anthology which contains the story 'hatchling' about a woman who has spent her whole life changing her personality in order to cater to various groups however reaches a problem when she has to invite all the groups together for her wedding. whilst initially this story was just one crazy story amongst much more insane ones (if youve ever read any murata you know what i mean), after some consideration i realised i very much do the same. 

when im with my best friend i tend to act childish and needy, with a different friend i act mature and studious, with yet another i act fearless and outgoing, and so on and so forth. the worst is when i have too many people at once - then i just shut up and withdraw.

after some googling i found something called the chameleon effect, which is when you mimic certain traits and mannerisms of the person/people you are talking to in order to appear more likeable. whilst this is very common, i feel like i have a much more intense version of this, to the point that i have no idea who i really am. this used to work well for me overall as ive been pretty well liked however ive noticed recently that the people ive considered my closest friends starting to avoid me. i fear that theyve begin to consider me disingenuous, or perhaps simply dislike me ive been presenting to them but i just dont know how to fix it. i dont change the way i act consciously, but its so deep-rooted inside of me that even if i started trying to stop i wouldnt be able to because it extends to even factors like my speech patterns and the amount of times i trip when walking.

do you guys do this and to what extent ? should i try working on it ? or just leave it as it is ? where do i even start ? please give me your thoughts on this !! 

sorry if this felt clunky, ive been thinking about it for a while and just wanted to get it down
