Well, just from reading this, I can tell that you have great potential, not just as a hirable economic agent but, more importantly, as a human being. Being "qualified" according to some company's stupid protocols (which may, for example, just be biased to whether you can follow rules) says nothing about you. So don't feel bad. And speaking of you—the real, internal you, not the you as measured by external social institutions/norms—I completely agree that you should keep learning what you like to learn and finding ways to express yourself.
As for jobs, in the short term definitely consider other jobs (e.g. I recently got a job as a math/CS tutor, pivoting away from my previous software job), or worst case, beg for some shitty job for now and/or ask for assistance from family/friends/etc. Doing so requires humbling yourself in that external sense (like the external sense of being "qualified") but that external you is not the you that matters. So keep fighting for (and improving) that real, beautiful you, whatever it takes!
