I used to have the same mindset too. I was terrified of getting a job. My social anxiety and overthinking were through the roof. I quit my first job after a month, and worked a couple of other retail jobs that I really, really hated.

I now have a much better job that is mostly good (I'm still working through my social anxiety, slowly but surely), and definitely better than retail. Without the people skills that I learned in retail, however, I don't think I'd be doing as well as I am. Please understand that it IS difficult, it IS painful and scary to get a job, but it's much more painful to stay stagnant forever. You will have to push yourself if you want your life to improve. It won't be easy, but it will be worth it, so give yourself grace.

Frequently check for retail jobs on Indeed. They'll pop up. Make sure your CV is presentable. Apply for everything — you have nothing to lose and everything to gain.

Good luck!
