She does say that, and I believe her, but I also think she uses it as a copout to justify not making content.
She had a pretty regular streaming schedule 3 years ago when Jedi Survivor was out, and was playing Battlefront almost every other day at one point, in addition to reacting to every new SW show too.
I don’t think it subsided that entire time and it’s miraculously got worse now. I think she has chronic pain, had always been dealing with it but has lost interest in making videos/streams and uses her chronic pain as an excuse to not do so.
