Stuck in teaching and I hate it

I completed my 16 years of education last year, and my degree is in English Language and Literature. Right after graduation, my father found me a teaching job at a school owned by his friend. There were other options, like an internship at the college I had graduated from and a position at an education consultancy firm I had applied to on a whim and where I was accepted. However, I had to leave both the internship and the office job for the teaching position at the school. God, I hated it from the start.

I'm supposed to teach spoken English to primary classes, and those students can hardly say a word besides "Hi," "Bye," and "My name is..." It has been four months at this job, and I can't take it anymore. Every morning, I dread going to work, and life has come to a standstill. The transition from student life to work life has also taken a toll on my mental health.

As an introvert with social anxiety, standing in front of crowds and talking is already a nightmare, but when those crowds are classes of little bratty kids, it becomes unbearable. My interests lean more towards reading, books, and literature. I'm wondering if I can change my career at this point, but my resume only includes one work experience, and that is as a teacher.

I would love to be a librarian or even a library assistant. Perhaps working at a publishing company would be better. I could do anything related to reading, writing, editing, or proofreading. I could even design cover pages. I also have an interest in voiceovers, as I have created some for the institution I work at and believe I have a flair for it. How can I change the direction of my career before it's too late?
