Sisyphus

That's it, thank you so much! I can't believe it was in this thread the whole time

I'm looking for a story I read in 2016 about a woman who goes on vacation (spring break?) and is mistaken for a lost child. She loses her ID and luggage. I think it was set in Hawaii. At first she stays with a social worker who gives her children's clothes, and is later put in an orphanage. At one point she goes swimming on the beach with other kids form the orphanage and wears a (green?) one-piece with an embarrassing design on the front (teddy?) on the front, and sees people she knows. She has long hair. The kids at the orphanage shave her body hair off. Has anyone read a story that sounds like this? It's driving me crazy
