Don't know where I am going or even where I can go

What do you do when saying 'no' would lose you a big chunk of your income, but saying 'yes' would be madness?

I don't know why I am asking you, I have already said it. I suspect that panic and worry will set in soon but at the moment I am feeling reasonably calm. I'm going round with my survival tune in my head.

The bare necessities of life will come to you
They'll come to you!

But will they come to me. :-(
