My core username is "scattered". I have been using it on and off since 2000. I often feel scattered in the sense of fragmented and pulled in various directions. In addition to that, I had recently published a research paper involving somnething called scattered sets in general topology (a branch of pure mathematics that I had specialized in while in graduate school) so the choice of the word "scattered" was in part motivated to provide a secret link between my internal and my external life.
"scattered" has been a sometimes troubing quasi-alter/part/persona (I am DDNOS rather than DID) that gives voice to things online that I would never speak of in real life to anybody other than my therapist. Periodically I have tried to get rid of "scattered" in futile attempts to bring my internal and my external world into better allignment. This has involved me repeatedly (over a dozen times) doing something like creating an e-mail acount such as
scattered@yahoo.com and using it to create a google account to post to usenet groups (such as alt.support.dissociation) or join some mental health forum, only to delete the accounts and e-mail addresses after a few months. But then I feel the desire to ressurect "scattered" after a few months of no internet. But when I try to create a new yahoo (or gmail or whatever) account I find that I can't use the same username. So - I pick another one such as
too_scattered@gmail.com or
still_scattered@yahoo.com - something which has "scattered" in it. A few months ago (after little participation in the internet for about 6 months) I started feeling scattered again and my attempt to find a username that would fly with gmail led to "rescattered". I rahter like how that sounds since I do feel scattered again after a period of feeling more gathered. Hopefully I can resist the temptation to delete the latest incarnation of scattered.
