I've been doing this so long that when I try to picture myself doing anything else, I just can't. Even on the bad days, when I know I'm unhappy, the door out doesn't feel locked. It's that I genuinely can't see one. This is the only version of me I can imagine anymore.
More people experience this than they realize.
You've done this so long you can't picture yourself as anything else, and that keeps you stuck.
