my life is messed up only because of 1 person

i have a brother, he is weird.. everytime my dad takes my phone away and were home alone he touches me inappropiately. and yes my dad wont do a thing because its not a big deal. but deep inside it makes me to HATE my dad and brother. even if i was about to die, they would'nt help me. and yes they are my biological family, which is why people dont understand why i hate them. i have no one to even directly tell this story to, i feel guilty for getting to have such people in my life :(
