It is very difficult to make your family stop treating you a certain way because they are used to it.
I am proud of you for achieving whatever it is you wanted.
I think communication is the best way to let them know that you don't like the way they treat you. I mean if they don't know that they are wrong, how will they change it.
Instead of confronting, you can have a nice discussion or conversation with you family.
If you feel like that is too much, maybe write your thoughts down in a letter or message or email and send it to them.
