Yeah, I think she's probably fine.
As with various celebrities, she may just have trouble turning off sometimes. She seems to post a decent bit about like "I waited in line for 30 minutes... that's such a waste of one's life isn't it?!" Like... she has to constantly be going and doing something all the time.
Just this morning she talked about how she had to wait 160 minutes for this kaitenzushi place her and Aika went to, and how that was a waste. Then again, 160 minutes isn't really negligible either lol so that doesn't necessarily count.
Just from what I've seen otherwise too.
She's just too much of a little ball of energy... She sure looks more awake normally than Sayu or Eri for example, lol.
