My mom doesnt understand my sexuality

Amy

So I came out when I was 11 (yes 11) as Bisexual. I always knew I wasnt straight and I knew Id love both genders and I came out. My whole family supported me but my mom. She said it was going to be a phase and told me to keep it a secret to the other side of the family and never spoke to me about it again. Im 14 now and I realize Im pansexual and have been in one relationship with a transgirl and Im so happy with my sexuality and so proud but idk how to have that conversation with my mom again. Im scared of her shutting me down or straight up disowning me. She never talks about LGBTQ with anyone and gets awkward around any of my gay friends. Help. I hate hiding from my mother.
