im not sure if im a system or not.

I have created these i guess personas (im saying personas because im not sure if this is a plural/headmate thing or if its just imaginary friends or personas or something) and I sort of switch between them. I dont think persona is the right word because they arent versions of me they are like their own people but still "me" I dont know how to descibe it and currently there are only two of them. There used to be another. This has been happening for a long time but im not too sure how long because at this point it just seems normal to me. Its been happening long before I even knew what a system was. And I'm questioning whether this is some sort of system thing (but I dont have any amnesia between when I switch between them which makes me think its not yk?) And I dont want to fake being a system but I'm not sure if im a singlet.
