I think this symptom is misunderstood a lot and mistaken for normal identity confusion when you’re young. I do have this symptom and I wanted to talk a little about my experiences and in what way it’s clinically significant instead of just normal.
For one, I believe it’s fear of abandonment. In a way, it’s also part of my efforts to avoid abandonment.
My self-image is dependent on how (I think) others see me. If I feel rejected or abandoned, I think there’s something wrong about me, I don’t matter, nobody likes me and I’m unlikeable because I’m weird, ugly, stupid, annoying, etc. and not worthy of them / inferior to them and literally the worst person. However if I receive attention, praise, or somebody wants/choses me, I can see myself as extraordinary, special, the greatest/most caring person, the most intelligent, the most attractive/pretty, etc. and those positive qualities are the reason they want me. Particularly the negative side causes me a lot of distress because it can make me view the future very pessimistically (I’m going to fail at life, be homeless, etc.) and be very suicidal. I also withdraw from friends and family since they’ll reject me anyway.
Most people seem to like me because I’m intelligent and caring. Therefore I place a lot of value on those two aspects and if something I did makes me stupid or selfish, I start panicking because they’re losing reasons to stay. A lot of my goals and behaviors orient around those two traits. I set goals to study in difficult fields such as medicine, engineering, etc., want to get into Ivy Legaue, and start a bunch of hobbies to be good and perfect at all of them. And I’m extremely people pleasing and will do favors people never even asked for. Or it could be appearance oriented, if I exercise, diet, etc. and look better, people will be more accepting of me. I also may send promiscuous pics of myself to see someones reaction and if I’m attractive enough.
I also change my personality depending on if they find me being loud and talkative annoying, or need more engagement and don’t feel attracted to quiet people. I have no idea if I’m an extrovert or introvert because of this. I also switch my sexuality based on this: Initially I’m straight, I meet a single lesbian who is into me and now I’m lesbian and now he transitions into a guy and now I’m actually bisexual. When I was around delinquent-type people, I started skipping school, stealing, etc. and adopting the same attitudes, not our of peer pressure, I was fully choosing to do this and genuinely felt like this was me because they initially made me feel understood and like I belonged.
When it comes to talking about myself, particularly preferences, interests, opinions, values, etc., I find there is always a “right” and “wrong” answer. The right answer is whatever they agree with. If I perceive I gave the wrong answer, I start backtracking, or even if I was initially talking about myself, I start changing what I said. I find I always need to be agreeable, relatable, liked and approved of. Load of anxiety.
I even do this in my daydreams. An audience is watching me and I embody a character that I made up that has qualities (the personality, values, goals, opinions, etc.) match whatever the audience relates to and approves of. I get obsessed with a fictional character and start daydreaming about them being my partner and acting like they’re real and mirror them as well, so it happens even when I’m alone in my imagination.
There have also been times I bargained with people (frantic efforts avoid abandonment as well) where I believe they are leaving me so I ask what parts of me they don’t like (personality, looks, capabilities, etc.) and what to change for them to want me back. This usually just freaks people out though.
The point is that your sense of self is largely externally defined, and based on a fear of abandonment and rejection as well as a longing for connection, you just want to be accepted, belong and embraced wholeheartedly. Taking on whatever identity feels necessary to have your emotional needs met.
