Trouble

I have one week to find a job or I am in serious trouble.
Why?  I have used up all of my unemployment insurance.
I am not hopeless but I've applied for more than 140 jobs since I was laid off in January and haven't got one yet.  I had an interview yesterday for a delivery driver job but I think they thought I was too old.  I walked into the office with a gray beard and wearing a tie.  Everyone else was 21 and wearing a t-shirt.
I'm just not getting any call-backs.
