[wowenglish1]

I'd like to know the meaning of "upset" in the next article.

Results are based on telephone interviews with a sample of 1,510 adults, age 18 and older, drawn randomly from the American Red Cross database of applicants seeking assistance due to the effects of Hurricane Katrina. Interviews were conducted Sept. 30-Oct. 9, 2005.
Thinking about the day Hurricane Katrina hit and the first few days after that, can you please tell me the kinds of emotions you were feeling at that time?
