I don't know how to properly explain this, but I'll try my best.

So before I found out I had BPD, I thought I might have DID or OSDD, due to me acting completely differently out of nowhere. 

I know that obviously people for example act a certain way around their friends, and a completely different way around family or at work. That's not what I mean though. I could be talking to someone, then suddenly I dissociate and then I talk differently, act differently, have different opinions, and even want to be called a different name.

It's always me though. It's always me who is conscious and doing all of these things, but no matter what way I may act and which opinions I may have, it always feels natural and like that's just who I am. As soon as I "change" to the next "personality" though, whatever I did before feels like it was absolutely not me, I don't even feel responsible for what that "other part" of me did, and I feel like that current "personality" I'm displaying is now 100% me. Those "personalities" are all reoccurring as well, and I have certain ones that I display more often than others. 

Does anyone else with BPD experience this or know what it might be? Does anyone know if that's even a part of BPD or something entirely different? I'm majorly confused about this, because it's obviously not DID or OSDD (since again, it's always me who's conscious and I know that) but it's also not something that I've seen happening with anyone else. Thanks in advance!!
