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.
