I’m so done

I walked out to my garage to ask my parents something and out of no where my dad said “wait let me see your teeth” I did and just thought it was really weird. He then turned to my mom and said “I think she needs braces, don’t you think” after hearing this I decided to put in my thoughts and said “I know my teeth are slightly crooked but I don’t want braces. If I were to do something about it I would get something more unnoticeable not flat out braces.” But my dad turned to me and said “That’s not for you to decide. If I want you to get braces, you are.” Keep in mind I’m 17 about to go into my last year of High School. So I pretty much said, well since it’s not a matter of life or death, and doesn’t affect me I don’t think you could force me to. It’s only a matter of looks. All of this I said respectfully. My father is a lawyer so usually he tries to get all the facts and opinions before deciding something. He then pretty much said that since I’m still a minor he can and will make me and will get a court order to do so if I refuse to be cooperative. So pretty much my Dad threatened a court order on me to change something about myself and is trying to force me to do so in a certain way that I don’t want. I also suffer from many mental problems (depression, anxiety, e.d.s, overall I have trouble loving myself) and right as I was almost to the point of truly loving who I am, it gets torn down. I just can’t anymore, as soon as I’m finally happy something happens and I’m viciously thrown back to the starting point...I just don’t know what to do anymore and I’m almost to the point of just giving up completely. I don’t know, am I overreacting? Is my dad is right and went about this the right way and I’m taking it all wrong?

TLDR: My dad is trying to force me to change how I look, and is trying to male me take the method I don’t want to do in order to change that part about me. I don’t know who’s in the wrong here.
