IIRC she's mentioned that she has ADHD but I think she's also bi-polar. I watched that RDR1 video you guys were talking about and it's pretty alarming. She's a crying, babbling mess then switches to her normal voice seconds later and starts speaking calmly. She hires and fires editors non-stop, hates her mom but then posts pics with her, deletes tweets when she gets called out then cries about it, sub tweets other streamers constantly etc.
I think the whole group that came up around the same time (Marz, Tofu, SRG, Agirlandagame, Alyska, NukaEle etc.) fell apart after Briana (SRG) started to do her own thing after the FF7R announcement and moved to Twitch. Nowadays they just stream on Twitch and rarely post on YT, Agirlandagame is the only one who still does YT videos consistently. There was also a Youtuber named EmJems who had a "early Marz like style" and was apart of their little group but she just straight up disappeared from YT & Twitter one day and hasn't been back.
