I know how it is to switch ego states. For me it is totally normal. It might even be common, I think it is one of these things people simply don't talk about. The worst is to be inbetween them in my case, it is being peeled off everything but the very basic personality traits.

I've also been seen from the outside and been suggested I was bipolar but it's not basically about moods seen from the inside.

My memories form very strange, I don't ever push anything out of memory, I remember in detail, but there is something lacking, the mere feeling that those memories are me, the me in the past.

I think this is a very interesting thing, and like I said probably not too uncommon. I think this also is the correct section to do it in. Most likely to have other people see, and maybe get good replies.
