The complete version of this sentence was: " Regret that I didn't go to school. I'm not afraid of being uneducated, but I'm afraid that I'm not worthy of you." This sentence came from a novel,'Battle Through the Heavens'. It was a reflection of the main character, Xiao Yan, on himself. He thought that although he had read a lot of books, he had not been able to learn more knowledge and skills for various reasons, resulting in him not being outstanding enough in some aspects and not daring to be with you. These words expressed Xiao Yan's inferiority complex towards himself, but at the same time, he also expressed his love for you, hoping that you could accept his shortcomings and grow up with him.
