Girl does not know how to slow down and still continues to volunteer and do charity, so she's been breaking her back over that as well. I'm sure her childhood nanny not doing well is the major reason, but she also needed to take a break in general. She can be a bit dumb sometimes, but she's a hardworking girl and I'm glad she's taking a break.

So this paired with her Lyrica tweet, it's safe to assume that she indeed went back home to PH.
