I am so sorry you are going through such a tough time. I was in this boat for a few months. I had rent pending and needed a paycheck asap so I could pay it on time.

One thing I learned through my job search was that the more jobs you apply for the better your chances are. The job market is very hard nowadays. There was a week where I set a limit to myself - minimum 50 applications a day. It took me a few hours each day but really helped me confidence - because the more I did the more likely I would be to get a response.
After that week, while I was submitting my 50 for the next day, I got a hit from the job that is now my current place.

Just relax. Things will be okay.
