Who cares if someone tells you that they think you're making this up? You know what's real. You know what goes on inside your life and mind better than some doctors would. You know what you experience and feel. If someone thinks that you're making this all up, either they didn't evaluate you correctly, they don't believe in DID, or they're unfamiliar with dissociative disorders (or they're just plain bad therapists). Remind yourself that you know what's real, you know what's true, and make lists of the symptoms you've felt, the dissociative experiences you've had, the proof that it is DID, and read it whenever sh*t gets hard. Know that just because they're therapists doesn't mean they're always right, nor does it mean that they'll always be competent, and realize that while there is a chance that they could not "catch" anything, that doesn't mean there's nothing there, and it certainly doesn't mean you're making this up. Stay strong in what you know to be true, and don't give a flying f*#k about what other people say or tell you, especially if they obviously don't know what they're talking about. No competent therapist should evaluate you and go "yup, faking". Because even if this wasn't DID, you are still having symptoms of something, you are still experiencing something, you are still struggling with something, and that something is very real, and cannot just be written off as "you're making this up".
