Fitting in costs more every year. Standing out on your own terms is surprisingly cheap.

Matching a group requires continuous adjustment, and the adjustments get more expensive as the differences between you and them become more real. What was a minor edit at fifteen becomes a career, a set of opinions or a way of living that is not yours. The alternative is less lonely than it looks, mainly because it attracts people you actually match.

Notice one thing you do purely because it is expected. Stop doing it, quietly, and see who is still there and how little anyone mentions it.
