So the issue with the "fake DID" thing is that
Getting a proper diagnosis is a fucking nightmare. Plurality isn't taken seriously by the majority of mental health care providers and ones that do often fall into "become singlet to be Perfectly Mentally Healthy" territory (again, speaking from experience). A lot of people fall into the similar "if you don't have every symptom exactly and didn't get a professional diagnosis that can cost thousands of dollars you're clearly faking for attention." mentality you have, and I honestly hope you break out of it someday. Gatekeeping doesn't help anyone.
