What should I do if I feel embarrassed to go out and look for a job without a degree?

Then improve yourself and improve your self-confidence. In fact, you don't have to feel inferior when you go out to find a job, because there are many jobs without academic qualifications. Not everyone has a high degree, but everyone has found a job, so you don't have to feel inferior. It's no shame to support yourself by working. Of course, you can also improve your education, such as attending an adult university, so that your education will gradually improve and you will get more jobs. Therefore, the way to solve the shame of going out to find a job without academic qualifications is to improve academic qualifications and self-confidence.
