Impostor syndrome with a side of my-family-is-controlling-my-life-even-though-I-don’t-live-with-them-anymore (this feels like there’d be a single word for this in German or a similar language)
I suspect that this is more common than we realize. There are the obvious cases, like you and me, but since I got clear I’ve realized that it frequently doesn’t really look controlling to an outsider and that even from inside it can look and feel normal without actually leaving you free to be yourself. Now that I know what to look for, I see a lot of people living their lives to family (and other) standards that do not allow for personal growth.
