A question I need to ask and some backstory. [ Parts of a Vent ]

TW - Denial spiral, mentions of being crazy / insane / ect.

I've wondered over this question for almost 6 months, it genuinely eats at me. Are there any other disorders / mental health things that cause alters and other people in your head that aren't DID / OSDD ?

I've had 4, they all have different personalities, i know one had different likes and dislikes than some others so I'm assuming they have different likes and dislikes, different genders, ages, they feel different, feel the need to speak different, feel the need to act different, and they don't feel like me.

I'm an age regressor myself, at first I thought it was just different headspaces for that type of thing, but i think i was wrong. The amount of differences between them and myself are too great, while i only know surface level information, I can feel the differences.

They come and they go. The longest anyone has disappeared for is 64 days, it's been 62 days now, since the last appearance of anyone. I don't have inner communication, outward communication, I don't feel them anymore, I do experience dpdr, I don't understand the definition of disassociation is, the "feeling like you're in a mist, time slowing down" I don't understand that so i cant tell you if i experience disassociation.

I experience time gaps, i have a horrible memory that's only getting worse. I have certain feelings that haven't happened since I started questioning and researching.

At one point a few weeks ago, before I was falling asleep, I heard parts of conversations, I heard people ( or different vocal pitches I could say ) calling my name. I heard so many different people, at least 3 - 4, it was weird, but I know auditory hallucinations are a thing, and the brain is always playing tricks, so I'm trying not to think too much of it.

Something that confused me once, is when someone showed up, i think i was doing something they enjoyed. They told me their name, that they liked the activity i was doing and immediately went away again, it was interesting, but i don't want to think too deeply if it's just a normal thing.

Another time is when I was speaking with friends, i felt the presence of someone else, I know my personality and it was different. Their speaking pattern, the way they spoke, i immediately knew their name, it was just there. It only lasted a few moments before they were gone. They never seem to appear for more than a few minutes at best. It's confusing.

I often wonder if im not ready to know or unlock this part of me yet because of unknown situations or dangers, then why make me wonder, why make me worry, why make me stress, why take over my thoughts, why not make me forget, ive forgotten so much already, why not just take this away until something or someone else decides im ready, if you're going to put me through this at least check up every few weeks, once every 2-3 weeks, a specific day a week, like a Tuesday, or a Saturday. Just something, don't leave me here with my own thoughts. This is scary, i hate it, i want it gone but i also want it back, if you're going to be here than be here, i dont get it, i dont know if i want to understand because what if i cant do anything about it, ill have no choice but to sit here with this until i can do something about it myself, and god knows that would take even more years, this shit sucks.

I'm not looking for a diagnosis, Internet people can't do that for me, I'm aware. I've researched a bit, I know specific terms I should be using, but if I am just a single person I don't want to offend or feel anymore like a fake than I already do. Getting this off my chest and asking that question at the beginning seems helpful for my own peace of mind. Hell, I think I'd go crazy if I kept this to myself, I can't have myself going insane at this age. Lol. I'm going to sound so insane if I find out one day that this was just a weird escapism thing. But yeah, what other disorders, if there are any, cause alters / different personalities, or the rest of this stuff ? Also, if this is just normal human being stuff that everyone goes through, tell me. If im going crazy and not making a lick of sense ? Tell me. If i should just give up ? Tell me. Thanks.

Also tell me if i need to change the flair, couldn't decide if i should do the TW one or the vent, the TW one seemed misleading for mine but i could be wrong.
