Have an exercise routine, have small goals and list your skills and strengths. Next, stop spending uselessly. Sell your junk, downsize everything before your job is gone. Get used to living way way way below your means. Having money in the bank helps in situations like this.
Ask friends for leads to future opening for jobs with your skill set.
Last but not the least, remember what you wanted to be as a child and start working to at least get connections in that industry.
Did you want to be a doctor? Ask if you can be an orderly or a janitor. Be around your dream and new opportunities will open up.
