I wanna run away from home

I don't want to be here anymore, my mother doesn't like me, she always yells at me. I'm scared of her. And when I don't tell her things she gets even more mad. But how could I trust her when she doesn't even care about how I feel? Never did she ever ask if I'm okay, or anything. And then she blames me bc I didn't tell her my problems. But when I did try all she did was yell again and tell me I'm overdramatic. I've been swallowing all that stuff for years and I'm so close to just finally write her a letter and just run away from home and idc how much trouble I might get in.
