Thank you guys for replying.
Things very hectic now. Not sure why all this started. Started before yesterday I think.
(refresh trigger warning)
System structure is falling apart. I'm stuck inside taking care of injuries. Tetra doesn't feel like a good protector anymore, shadowshifter was our comforter and he feels like he's failed too. Vilkai and Moon aren't here to help us figure this out, we are in the void right now, they should be kinda close normally

I think this is going to take more than a break...
A bit of an explanation (long):
Tetra, Mend, and I have been cohosting because it was getting to be to much for me but im the best for it.
Mendax used to think she was a character, she got to know two others really well and she really cared about them. She still tries to get the other 2 players to RP with her sometimes, and she gets kinda down whenever they she goes alone for a long while. Well one of the players was rping with her a few days and his phone died, she got kind of upset, and then he wouldn't answer for another couple of days

Incidentally this is our SO, who happens to never have his phone on him, so we tend not to worry too much. But then he didn't show up to school and neither did his brother, I started to get kinda worried. Turned out it was nothing; they just stayed home and he forgot to charge his phone.
Until we found this out Tetra decided to give both of us a break, we were both pretty stressed. She bumped into him and asked where he was and he just said he wasn't there. Tetra got angry cuz she was already stressed from daily stuff, and our dad and all that. So she yelled at him a bit. Then she wouldn't atop apologizing. I dont think we've ever seen her that guilty before...
She and Hexa are what they both call "demonkin", which to them is basically "we're-demons-so-we're-not-friends-but-I-won't-kill-you-and-maybe-we-can-torture-some-others-together". Which is how they used to be, and so they sometimes get along and sometimes fight. Today was a fighting day.
Bluh. I feel drained writing all this...)
Shadowshifter normally takes forms of friends to help calm us down by talking to them. For some reason Tetra saw him and just got really angry (this friend of ours happens to also be multiple, sometimes she and one of his alters fight, I'm guessing they fought recentlyt without us knowing?

)
So she attacked him and Mendax tried to jump in the middle of it because, well, this is the other player...
So now Tetra has been going through a series of... I dont know. Modes? That she hasn't gone through in almost a year now. "Poet" "Death" "Music"... Not-Normal-Tetra-but-still-Tetra states. And recently she's not been herself either, like sometimes shell say something extremely pacifist which isn't like her but its definitely her saying it, like "NO! dont hurt that bug its still a living thing" or "dont pick the flowers! You're killing them". (she's been doing this both internally and externally).
I am really worried and don't understand what's happening. There is only one theory going around inside right now that I can make sense of : that maybe Tetra is a bunch of fragments or even a multiple. Both are really weird to think about... But it makes sense...
Sorry this is so long...
