First of all, I think you can work harder and strengthen your ability, so that your future will be brighter and your career will be more successful. Let me give you a simple example. Isn't Ma Yun very handsome? But why are there so many people called Ma Yun's father? Not because he has a successful career, you will have many admirers in your career, so your inferiority complex will be satisfied.
Secondly, I think you seem to have other specialties. You can practice some similar singing methods. For example, many people will be moved by beautiful singing nowadays, such as China's good voice, which means listening to your voice regardless of appearance. It's actually a good choice for you to strengthen this ability. If you sing well, of course, this is only an example, then someone will worship you and be moved by your singing.
So I think ugliness has nothing to do with it. After all, it's just a piece of skin. I think if you increase your inner self and make your heart better, then someone will still love and care about you. When someone praises your inner self, I think your inferiority complex may just disappear.
