Depends what you mean by “crazy”, I suppose.
Specifically DID? No one in my family I know of.
I have a laundry list of mental health issues, so I might qualify.
But the only person in my family who has been institutionalized was my one cousin. I think he was getting violent before they got his meds right.
I’m so tired of hearing people spout QTM bullshit. Good on you, stranger, for calling it out.
