If you're not sure if you're multiple, by all means, don't try to shove yourself into a box. I, myself, am having a bit of a falling-out with my mid-continuum self-diagnosis, and I know exactly what you're talking about from what you've described. Sometimes it's easier to talk about different fragments of personalities with names, but you can also get carried away in your paradigm and add a lot more frustration than you already have. For example, I'm missing a few years of memories because "someone else" has them right now--but that someone else is a fragment of me, so there's no method of communication, etc... I don't mean to steer you away from multiplicity if you think it applies to you--but I warn you to not get wrapped up in the idea if it doesn't fit right.
