Reddit mentions of THE STRANGER IN THE MIRROR: Dissociation: The Hidden Epidemic

Been there! It sucks losing an argument with yourself XD.

My 💡ah-ha moment was realizing that I had one person freaking the fuck out, and another insisting "we're fine, nothing to see here" and a third going "what do you mean 'we'...?"

Chances are, you're not overreacting. Yes, people go through phases or have difficulty with identity confusion after major life events (teen-years, divorce, new baby, etc.) but what you're describing certainly sounds more like a median system, which is common in DDNOS/OSDD.

I'd strongly recommend doing a little reading on the topic: Stranger in the Mirror and The Myth of Sanity helped me feel a lot more secure in "yes this is actually the thing, and it's like 'normal'/healthy people may experience, but more so." Stranger in the Mirror has an adaptation of the SCID-D that you can use to gauge the severity of certain symptom clusters, and instructions on how to interpret that.

There's a lot of terminology out there. Some people don't like "main", "host", etc, but it depends on each person, really.

I personally love answering questions, as long as they're asked respectfully. I know a lot of people are worried about offending me, but really, I know when people mean well and I'm rarely offended. It wouldn't hurt to ask her. I know I would rather be approached by my boyfriend with a request to talk to his sister than directly approached by his sister, but I'm sure it really depends on your relationship.

I did a /r/casualiama on my DID a little while ago. It's here if you're interested in that. A couple of book suggestions as well:

• Switching Time -- This is my favorite "account" book. It's written from the therapist's point of view, which I find fascinating, personally.
  
  
• The Stranger in the Mirror -- This one's less story-like, more academic. It explains the elements of DID.
  
  
• Multiplicity -- This one I would not necessarily recommend to people with DID, but it's definitely great for those that are trying to understand it. It's not about DID, but about the elements of multiple personality that most everyone can relate to.
