I tried to come out

Hi.

I'm a lesbian human. I've known for two years now. I tried to tell my mom but she thinks it's for attention and doesn't think it's true because " I didn't show any signs of liking girls growing up" which yes I know is bull shit. She says she would support me if I'm still gay when I'm older but I really feel like she's just saying that out of obligation and I don't understand why she thinks it's all for attention. My brother keeps telling me it's a phase and I'll get over it and my dad is super homophobic. Help me.
