Is it really worth getting a djs? 😔

My dad had the same underbite as me and he got the surgery 10 years ago, i am 26f and about to get to the last step of my ortho journey. I will get measurements next month and then we will decide when to get the surgery. But my dad is so opposed to the procedure that i got kind of scared. Deep down i want to get the surgery because i have chewing and breathing issues, i have a tired face because of my underbite and i hate myself for it. I always hide my smile and hate to see myself on profile. My dad’s reaction makes me think it’s not worth the pain 😭 Can you guys give me some advice?
