Okay, that actually sounds like a real trigger. I won't rage at you for that. I'm not going to blame the blog, though, because there's no reason they should have assumed they would need that. That said, you're legitimately mentally ill. I know I'd just be called ableist for this, but you actually need mental health professionals to help you. If this is someone hanging out with their vampire friends, all of those friends need legitimate mental care. These cases are exactly why I refuse to believe therians and otherkin do not exist, but also classify them as a delusion akin to the glass delusion. It's similar to clinical lycanthropy, actually. If this is one person with three vampire personalities, you have DID. Many of you "multiples" do not. However, if this is one person, they legitimately have DID (and their other personalities have the aforementioned unnamed because it's not official delusion). But, this is legitimate mental illness, and it was interesting to bump into it.
