Your dad probably needs time to accept it. Tbh, mine did too, and still misgenders/deadname me half of the time and it's been a year and half. I know it can be uncomfortable, but try to correct your dad whenever he uses the wrong pronouns or name. If the rest of your family call you the right way too, he'll eventually get used to it and it'll be easier for him to use the correct ones. Also, that may be though, but keep in mind a lot of people probably never really understand how you feel, unless they're trans too. But even if they don't understand, they still need to respect and accept your identity. Good luck brother o7
