Unemployed and Depressed

I've been unemployed for 6 months now. I graduated high school, had a great job, then got laid off due to the company deciding to shut down our warehouse. I was working fast food to get some sort of money and quit thinking I had enough saved up to last me till my next job. Months went by and I continued getting denied job opportunities, no warehouses, or even food near me will hire. I feel completely worthless and don't know what to do anymore. Family and friends have helped as much as they can but I still can't land a decent job, I'm getting to the point where I'm considering self harm, or how things would be better off if I didn't exist. What should I do?
