Nobody knows what it is like but you and those who are going through it.
People are going to Houston in droves, to Austin. Craigs list has a list of people all over the country who are helping with housing, jobs, etc.
But home is home and my heart goes out to you. Where are you living now? Did you get an apartment or house? I know people sleeping on couches. I have never seen anything like this in all my days.
I have the sense the churches are doing the heavy lifting and are committed to helping. But google on Hurricane victim help and check out craig's list.
I am in Baton Rouge for now--sleeping on a sofa. I am job hunting on-line in several areas and states. I found a house here that I could rent, but need to know I have employment here before I take it. Hope I can find something before it slips away--retail jobs available, but won't be enough to pay bills. I am really getting anxious and depressed.
