The word "Pollyannaish" is derived from "
Pollyanna," the heroine of Eleanor H.
Porter's famous novel "Pollyanna" (1913), whose outlook on life was one of absolute optimism and whose problems were always straightened out in the end.
(Disclaimer: Not very modern, but still an urban term.)
"Although I've been raped and mishandled by a
demon, I'm
determined to remain
optimistic, no matter what" is a perfect summation of being pollyannish.
