Hi Butterfly....glad to meet all of you, welcome to PC!
My biggest consolation in confidence of the condition would be the fact that here I am at home posting in this forum! Normal people normally don't feel compelled to be posting here, normally.
Some pop in questioning themselves with some concern, but mostly because they do have similar symptoms like hearing voices through other forms of MI, that is to be expected.
You do seem to have very well detailed characteristics of others that you seem to sound confident about, so I would dare to lean to the real side.
How you describe your earlier years sounds very similar to the way I describe mine, starting wth yesterday. :P
We tend to be hostless. We can only see who dominates the time out by looking to the past from the future. We switch to suit the moment as needed.
Hope to hear more of you and your system.
