To those who used to fake DID: Why?

Hi all, I hope this is allowed!

I know that there are people on this Sub who used to fake DID/thought they had DID/etc. I'm curious about why? If you decided to fake, what made you decide to do so? If you genuinely thought you had DID, what made you think that?

Also, what was it that got you to stop faking/realise you don't have DID? Is there anything that people said to you that helped?

I have suspicions/guesses, but I'd like to hear from people's experiences.
