It’s like feeling as if you’re in the Always Sunny episode “The Gang Broke Dee”, wherein the gang go to great lengths to trick Dee into thinking that she is a successful and respected comedienne, only for them to reveal that it was all a charade to belittle her more.
To me, that just sounds like imposter syndrome. You are assuming that others view you as competent while simultaneously believing that you yourself are not. Isn’t that basically imposter syndrome in a slightly different mask? One that is tinged with paranoia and trust issues, but still imposter syndrome nonetheless.
That part does not apply, and I understand it to be part of the definition of Imposter Syndrome.
