Ah. I've heard about facets before and I use that term to describe some of the others within me. What you describe, with being influenced by yours sort of sounds like mine, but they sometimes do talk to me.

I use the term facet to describe them because we are generally connected, and they don't have full control of the body. I also call myself a median system for that reason.

As someone else has stated, it could be OSDD.

Since you are unable to see a therapist, one thing I recommend is talking to people who have things similar to what you are describing, and maybe trying to document the other personality if you can.
