That must be really frustrating for you. I wonder if now is the time for you to think about what else you could do? Sometimes starting to look for something else will give you a purpose and perhaps make you less stressed and the teaching job will turn up.
However, you should start looking at transferable skills - somebody else was asking a similar question and I suggested they should look at

In addition, there is an excellent book "What colour is your parachute" see

I really feel for you at a difficult time, so Good Luck!
