Concerns about orthodontics

I wanted to get orthodontic treatment, so I consulted at several hospitals, but I was told that my lower jaw is retruded and that orthodontic treatment alone would be difficult, and surgery would be necessary. However, I am worried and burdened by surgery, so I prefer to resolve my dental issues with just orthodontics if possible. Is there any way to do that? I'm becoming more and more conflicted. If anyone has similar concerns, let's share information together.
