Isn't your head really noisy, and isn't it exhausting?
Not recently. Not in a way that we notice or are bothered by it in particular. But it used to be.
Note, however, that we are autistic, ADHD, and have c-PTSD. All neurotypes that involve a lot of rumination and hyper-active thoughts. We do have a constant monologue or even dialogue going as we go about our day, and sometimes it comes out of our mouth. We will even laugh out loud at or admonish each other.
Since coming out as plural, however, and finding that the Girls tend to have quieter minds in general, we have learned to stop talking over each other as much, to communicate with each other more in our subconscious mind, and to let a Girl front when we want to give our brain a break from excess conscious thought. And so, in recent years, our head has been a lot quieter than before, and we've been somewhat disconcerted by that. We are not yet used to it.
It is our natural state to be always thinking.
That said, when we have a major disagreement between system members, or our c-PTSD is deeply triggered, we will often feel extremely sleepy, sometimes dangerously so. Under such states, we exhibit all the symptoms of narcolepsy, except for the E.E.G. signals necessary for a diagnosis. And because of this, combined with other autistic and ADHD impairments, we cannot safely drive a vehicle or maintain a job.
The best thing for us to do in this state is to nap as much as we need to in order to resolve the internal issue. We will have intense dreams of what amount to staff meetings where we literally discuss what is going on. They can be loud and chaotic, and it can be difficult to take minutes, but the productive ones will leave us all memories of our conclusions.
If that doesn't work, then we have to have conscious group therapy to discuss things out in the open, so that the entire system can listen in using our ears, and so that the injured parties can feel like they have been heard and their needs truly addressed. Every time we have done this, we have returned to a normal state within a day.
And that is exhausting work. However, it is due to our c-PTSD, not our plurality. And our plurality, in fact, gives us tools for therapy that we might not otherwise have, to help recover from a c-PTSD attack.
Finally. When people ask us this question, it is usually in a context and a tone of voice that strongly implies the question, "Why be plural, if it is such a big problem?" or "Why not get cured so that you don't have think so much?"
It's really frustrating when people seem to imply that question.
We cannot help the fact that we are plural. We are not bothered by it. And our type of plurality cannot be treated or "cured". The things that lead our brain to develop as plural, namely our brain hemispheres' differing genders, are not treatable. And plurality is the way that our brain is able to function at all without the traumatizing distress of constant dysphoria.
