I'm scared of what she might think. She loves me to a degree that she'll probably accept it, but it'll be hard to explain to her

MY MOM JUST TOLD MY GRANDMA (WHO DOESN'T KNOW WHAT THAT MEANS) THAT I'M TRANS WITHOUT ASKING ME. I DON'T KNOW WHAT MY GRANDMA THINKS (I WASN'T THERE), SHE'S JUST OBLIVIOUS TO THE TOPIC, SO SHE PROBABLY WON'T BE UNDERSTANDING EVEN THOUGH SHE'LL PROBABLY ACCEPT IT. HURTS ANYWAYS. I ACTUALLY MENTIONED HRT LAST WEEK WHILE TALKING TO MY GRANDMA AND SHE DIDN'T GET WHY PEOPLE WOULD UNDERGO THIS WHICH MADE ME QUESTION IF I COULD EVER COME OUT TO MY GRANDPARENTS
