Buck up. We have had natural disastors like this in our past, see Galvaston, TX in the early 1900s something like 12000 dead.
Think about World War II 80 percent of the globe in conflict and the allies really not knowing if it would be possible to stop the Axis. That was some world is over despair kind of stuff.
Think about the fact that there are people all over the world going through as bad or worse stuff than this everyday, See Rawanda and the genocide that is occuring there.
My friend, things might be a tad bleak for us in the U.S. but things are far from over. Our problem/Blessing as Americans is that as a rule we are all spoiled rich kids who rarely have to deal with any major problems or strife so when we do get slammed it's hard. Think about somebody who gets poison IVY all the time. To them it's no big deal. To somebody who never had Poison IVY it is the worst thing in the world.
Don't ever let doom and gloom get you down because no matter how bad it gets there is always liquor
