The compartmentalized problem is serious, it's not easy and therefore personas should be sparingly used. You have to increase the points of trust to create any sort of sustainable persona handling system. These points themselves becoming stress inducers! When it comes to believing your own lies, one way to prevent that is to take persona creation seriously as if you are really preparing for a role or writing this character. Method actors have a bunch of external factors encouraging them to stop that persona, but for the rest of us we really don't so we have to create those factors. Whether this is a dedicated device with dedicated software, or physical cues to remind us who we're being. Youtubers are a great digital example of persona creation not being taken seriously. So many "jerk" characters wind up being really abusive people who just used that character as an excuse. Unfortunately, they're also a good example of how being haphazard with persona creation can wind up leading people to desperately link pieces of yourself to find the "real you" and reveal all that private information.
