Hi! I'm not always the greatest with comforting or the best with wording things but
Yes singlets can have memory loss
Yes singlets can feel like their body isn't theirs
But I doubt singlets have names and voices for their emotions
i cant be a system. i dont know why i cant, i just cant. every time i try to come to the conclusion its like nails on a chalkboard, something im not meant to know.
I think this is something a lot of systems struggle with, especially early on. DID/OSDD/etc are meant to be covert, and oftentimes that means hiding it from the people inside the body too.
My advice? Take things slow! Especially since your brain is rejecting so harshly, and you're already distressed. Things work differently for different systems but maybe a note or a directed though here or there could get you something? For us, it's typically easy to tell a thought from a headmate because (while the sound still sounds like it's coming from inside our head) headmates sound like they're behind whoever is controlling the body. But if it doesn't come easy, don't stress!
Research can also help! Learning things like journaling or communication techniques can help you learn more about yourself(s). Looking around on tumblr and seeing other people talk about their experiences can be nice too! But don't let it overwhelm you. There's no right or wrong way of existing!
Also, you don't always have to know everything all the time. It's completely normal!
