Constant misgendering from family

My whole immediate family knows I'm trans. I've told them all.

When I came out to my mom she immediately got me an appointment with a gender specialist who then immediately referred me to gender therapy that I don't need at this point in my transition. My parents are the kind of people that like to ignore problems until they go away so when I told my mom I wanted to stop therapy she looked relieved.

Now they're acting like because I don't need therapy I'm suddenly no longer trans?

Keep in mind, though, that the misgendering didn't only start with the ending of therapy my parents even on the day I came out to them called me a girl. My dad called me a girl in front of my therapist on my first appointment. It's just so unapologetic now? After I came out I could see that it was awkward for them to call me "she" and "girl" but now they don't even seem to acknowledge my feelings.

My parents have always been unsupportive and my mom has always been emotionally abusive (I don't think she realizes that though) and because of that I have a really hard time expressing myself, my opinions, and my feelings. Not to mention that my mom will probably victimize herself if I tell her what she's doing bothers me. I can't bring myself to tell them to use masculine pronouns for me and I sort of want to curl up in a ball and stay that way.

Even my sister who is the one person I feel the closest to in my life constantly misgenders me even though she knows I'm trans.

No one in my family even tries to understand that I'm a boy. Everyone just ignores me as if I'll "change my mind" or something if they drag this out long enough and keep calling me a girl.
It took me so long to come to terms with the fact that I'm a boy and it took me sooo looong to work up the courage to finally come out to my family and it's nothing to them. To them it's a problem they can just avoid.
