Had a temp job lined up but the client cancelled - rats

I had a temp job lined up to start this coming up Tuesday through Kelly Services.  The client changed their mind as to when they want someone to start.  I am really disappointed.  I know various companies and personnel agencies keep telling me how experienced I am, which is great, but I need a concrete job. This temp one could lead into full-time, which is why I am disappointed.  I know something will come up for me very soon.
 
All the best from Diane B.
