I accidentally came out

So.. I accidentally came out to my grandma and mom accidentally. I got a text message. My grandma thinking that I'm straight asked me "So do you have a boyfriend?", "Was that him texting you?". I said "I don't like boys, I like girls". I got so scared, because I didin't want to say that, the words just came out. I thought my grandma wouldn't accept me, but she kind of did. My mom was the complete opposite, she said things like "Are you joking? God made us the way that girls should like boys and that boys should like girls" I cried so much. What do I do?
