I don't think you are the only one who this happens to either. My system was also like a revolving door on a daily basis, and as we learned more about each other and began to function better we still had the super frequent switching thing happening, but became more and more co-conscious during it.
During more stressful situations though I guess you could say we had a deeper level of alts deal with things, and then it was more one (or one group) out at a time, with others pushed back, kind of what like you describe, I think?

And here's a little bit of something from one of our previous 'front revolvers' who is now just a part of me (no revolving necessary! ) -

You know what? It really doesn't matter what anyone else thinks or says about how it works for you. It is what it is, and it IS that way because that is just how it needed to be for you. There isn't anyone who can define your own reality better than you.
