Do I need jaw surgery?

I'm a 30 y/o woman and i'm concerned if I will need jaw surgery or not. I have a very small and receding jaw and my upper teeth totally covers bottom teeth but i don't have breathing problems, i can speak and chew normally, my molars are quite aligned and there's no gap in between when my mouth is closed, no sleeping problems or dry mouth at all. No crowded teeths neither so is confusing to me. Thanks in advance for your time and advice!
