> In my case I just proved knowledgeable and willing to listen and they reached out to me
If you put yourself out as a resource for people of a specific characteristic to reach out to you, then your exposure is far from a random sampling.
My broader point is that a random sampling of the population would never produce the quantity of actual cases of DID that is manifesting in young people on social media. In other words, the degree to which DID actually exists and the degree to which people claim to have DID have diverged dramatically in favor of the latter. That statement is not meant to be taken personally as I'm acknowledging that you've established yourself as a beacon for those struggling with this sort of thing to reach out to you.
