Yeah, I kind of broke down crying. I really felt like breaking something so bad and lashing out at how angry I am at myself.
Chipper up, fellow.
I've been where you are at. It's one of the reasons I participate in this thread even though I'm not looking for anything.
I went through a long spell as well many moons ago and it was most the difficult thing obstacle I've overcome since.
The key is not to define your self worth by your job. It's a hard mental shift. But society places a lot of performance anxiety on our livings. You have value, experiences, and talents that can make a strong contribution to this world. Everyone has.
Continue to apply for jobs, but look for ways to volunteer, help others (soup kitchen/visiting the elderly/sick), do some creative endeavors--game design, programming, music, drawing, etc.
Practice gratitude. You're not dead and you seem healthy. It may sound corny, but making list of things I was grateful for helped me immensely.
Also don't neglect your social and emotional needs. I know it can be tough if money is tight, but make time to spend time with loved ones. Their company will help you.
See if you can get some easy part time jobs. This is critical for your self esteem and will help you become a more attractive candidate.
One of my favorite quotes is, "Failure is not durable". Francis Ford Coppola said that.
It's tough, man. But life will seem very easy after you've cleared this hurdle. Think of the reservoir of strength you will be developing. Work stuff will seem easy in comparison. You will have more mental toughness than most of your work peers.
Press on, bud.
