For us, what helps the most is reminding ourselves that sitting in our room having hours-long switches and dissociation can't be faked. Why would I spend hours staring blankly at a wall for attention? There are so many symptoms of DID other than having alters that we can't ignore or boil down to attention-seeking.

We’ve ended up keeping a list of trauma and situations where we’ve switched for sure, as well as asking those around us for proof of switches. We remember it when we have bad faking moments n shit. Like solid proof that we’re not making it up.

i dealt with imposter syndrome for months about the system. i guess just at one point it kinda clicked for me and i was like "why would i fake this? this is horrible. i am truly struggling and this is real"

I've been struggling a lot with the same thoughts, it's actually manifested in avoidant behaviors like delaying appointments. I'm not sure who had the idea but we plan on making a huge list of every terrible thing we think about when we feel like we're "faking" to show to our therapist. Typically, trying to convince your therapist that you're actually faking and just a master manipulator will result in some very jarring reality checks for you 😅 at least it does for us, if you're in a safe place to be completely rooted in the reality of the disorder, I'd recommend trying this!
