While I'm not plural, the particular cocktail of neurospicy that I am has lead to an interesting and entertaining result
I join my first DnD campaign in 2015
Make Terra -- a changeling/vampire character who's supposed to be just a fun chaos character
I'm autistic and Terra becomes my main hyperfixation, far beyond hyperfixations of the past
Terra turns out to be the manifestation of my subconsciousness and their existence/working on their backstory is one of the most important stepping stones in helping me get out of my abusive relationship (long story)
I realize I have a love for writing and their backstory gradually becomes a novel
Novel writing is used as a very important tool in processing and dealing with my c-PTSD
I use Terra as a vessel to deal with a lot of emotions I wouldn't otherwise be ready to deal with, both in writing, roleplay, and day-to-day life. The character has become so much more than just a DnD character to me and actively helps me function and survive
Not a day goes by where I don't either think about or work on the novel(s) on some way
Timeskip a few years forwards
Be me, still haven't gotten any proper PTSD therapy despite knowing I've had PTSD for over 5 years (Only had fragmented light PTSD therapy, and mostly anxiety and depression therapy)
Between 2021-2023 I hyperfixate on DID (because I discover there is a lot of overlap between PTSD and DID)
Learned a lot of great things about PTSD from DID research, and it helped me compartmentalize and feel more in control some things that had been controlling me
Starts questioning if Terra is an alter (Spoiler: they're not, I'm just very autistic about them, but...)
Realizes that while Terra is not an alter, spending a solid decade using them as a vessel to deal with my trauma has lead to the character being More Than Just A Character to me, and they feel very real to me (while still fully knowing at the end of the day this is just my main hyperfixation character)
Sorting through hours upon hours of old novel notes
Comes across many notes I'd forgotten I'd written of the main villain -- the villain who's based on my abuser. Notes include a lot of dialogue that still holds up as well-written, manipulative and creepy
While trying to get into a sold workflow of sorting through notes, I keep regularly getting interrupted by Terra when reading the villains dialogue, causing me to shout out loud, in-character as Terra, things like "Oh shut the FUCK UP!" "Well that's a fucking lie!" "Uuuugh🤮!", "THAT'S NOT MY NAME DON'T FUCKING CALL ME THAT!" and so on, while reading the villain's lines.
Also at several times i have to pause to calm down Terra so I can keep working (while I'm feeling perfectly fine might I add). Most common thing for me to say is "It's alright. Look, I know you hate him but I'M TRYING TO WORK HERE!"
Remembers that these books are taking so long to write because every time I try to work on something related to the villain I keep getting interrupted by my own fucking character
I am well aware that Terra is just my brain's way of shielding myself from PTSD-related feelings, since going into character as them is what I've used as my main coping mechanism for a solid decade straight. I do think it is fun and comforting to have this character help me though
But I do wish they'd stop interrupting me when I'm trying to work!!!
