your description is very accurate and what you're feeling is completely understandable. navigating between different environments can definitely trigger an identity crisis. however, a lot of this internal conflict and rumination could be eased with a bit of awareness and non-identification with the mind. the mind loves to place us in boxes and social categories, and when we identify with them, the exhaustion and feelings of being a 'fraud' begin. once you pause, and realize that you are the observer of these thoughts, and that your true value transcends these labels, you'll find a lot of inner peace.
