If anyone here is missing out on lore as to why she would suddenly allude to "some personal family stuff happened this afternoon," as a reason to cancel stream:
Last October, both her Aunt, who was like a second mother to her, suffered a stroke, and, her brother-in-law, who was like an actual brother to her, suffered a severe motorcycle accident, and, has been in a coma ever since. This was a major reason as to why she took a hiatus from CC at the end of last year and this as well. So, my assumption is that one of them could've suddenly taken a turn for the worse, and, it was just absolutely horrible timing for everyone inolved.
Granted, I'm giving her the benefit of the doubt and being compassionate. I could be completely wrong, and I genuinely hope it's nothing that serious. But, her mentioning a sudden family issue made me immediately think of those 2 family members who are still in critical condition. At this point, I'd just allow her some grace and wish her all the best. Furthermore, as Rananculous and HugeGuy alluded to, she let's intrusive thoughts and brain-worms absolutely cripple her pretty easily, too. So, panicking about that, and, feeling helpless to do anything for her family right then and there would absolutely kill anyone's libido. :Sadge:
