Anyone got both Autism and DID?

or Autism and severe Exposure Anxiety (causing dissociation so severe you can only function by 'being someone else')?

I've been reading Donna William's blog about Autism and Exposure Anxiety causing 'multiple alters' and DID like symptoms.  As many here probably know Donna Williams has since passed away years ago and I wondered if there were any other adults out there who have both Autism and DID together? 

I can get Autism support from autism sites and DID support from DID sites but finding someone else who has both to ask questions to seems like an elusive impossible task!  PDA seems similar on the surface - Higher functioning Autistic people with more of an obsession of living in fantasy and creating persona's (sometimes said to be the only way they can meet demands), but how do you tell the difference of whether you have Autism and EA causing dissociation or you have Autism - PDA?  If there are not enough people with it or experts in that area?  

Thanks
