는데 어떡하다

but what do I do?

-는데 lays out the problem and 어떡하다 — a contraction of 어떻게 하다 — throws up its hands at it: 진짜 못 나가겠는데 어떡하지? (I really can't go out, what do I do?), 발이 안 가는데 어떡하니!. Every line here has that shape, and it is usually a groan rather than a real request for advice. Mind the spelling: 어떡해 is this verb form, while 어떻게 is the adverb 'how'.
