i hate him

my stepdad is insane.
Hes tearing my family apart and i cant take it.
He doesnt think he has a problem but he does.
I want him to leave.
No one is ahppy.
My mom is miserable.
My borther is too.
I just want them to be ahppy, but i dont knw what to do.
i never have known.
its jsut a stupid cycle of freakouts and suck ups and its never ending and i cant take it anymore.
I ahte them so much sometimes.
my mom for dealing with it and not trying to make herself happy.
My brohter for jsut accpeting his shit adn for putting us into this situation.
My stepdad for being the psychopath he is adn not seeing it.
and me for enver doing anything about ti but crying.
ITs so stupid.
