You are not failing as a person. Do not define your self-worth as you having a job or money. You are going through hard times. Everyone goes through hard times. That doesn’t mean you are failing as a person.
Take a short break from job hunting and pick it back up again. You tying your self worth to your job may be what’s causing undue stress thsts making it harder on you. It’s a job. It’s not who you are as a person. Understanding that even if you get a shitty job that pays the bills, it doesn’t decrease your value. Get any job you can, just use it as a breather, collect your emotions and thoughts and when you feel better level up to a new job.
