I am sorry to hear the stress that you are going through. I have been laid off 3 times over the last five years, so I know what you are going through. And, like you, there is not many jobs in my field of work which certainly limits your choices.
This may create an opportunity for you to find something totally new and different. Be able to explore other options that you may have never thought of before.
I wish you the best of luck and hope that you land on your feet.
