One Step Forward three steps back

Today I learned that the developer that was courting us to house our Art Center is likely stepping away from the deal. It is 12:40AM and I am sitting here AWAKE with knots in my stomach. There is a solution. There is a solution.... I will find the solution.
For 3 months they have been telling me this will happen, that they will make it happen... and today they simply said - We can't make it happen. blah blah - AC unit blah blah Stairs blah blah blah.
We left the meeting agreeing to try one last walk through meeting with city officials... but they were supposed to get me dates for the meeting and didn't. I'm seeing the writing on the wall.
Must go to sleep so tomorrow I can start fresh again.
