bouncing back after failed first round

I got hit with some terrible luck for this first-round interview with a bank I wanted. The night before the first round I had a very extreme emergency happen that left me up all night. I skipped class to try and get some extra sleep but was so anxiety-ridden from the event I couldn't. Come to the interview I completely bombed it. I actually connected with the interviewer and answered behaviorals well but just could not put the brain power together to answer easy technicals. I stumbled through them and gave some very poor answers (not technically wrong just very badly put together). I know recruiting season is still fresh but I am feeling in the gutter.
