I'm a 19 year old male, and my whole life my dad has been abusive to not just me, but my entire family. He has taken such a large toll on everyone's mental health in the family, and it's driving me even more crazy day by day. He loves to have control over everything and he wants everyone to know that he has control over everything. And when anyone in the family does the slightest little thing that hurts his ego, he uses the power he has to make them regret it. And oftentimes, it is with the most extreme punishments. I remember that he told me once when I was a senior in high school (I was still 17 at the time) that he would make me switch schools as well as kick me out of the house if I didn't do extra running workouts (I ran cross country in high school and he told me that he was going to make me do extra workouts outside of the training we were doing at school, and I tried to fight against it because that is a terrible idea and is just asking for injuries). I also remember that he told my brother that he "didn't give a shit" if he killed himself when my brother was seeking help for his mental health. And my mom can't do anything because she knows that it is useless trying to talk to him. That's why I haven't done anything when he does stuff like this, because I know that trying to talk to him is completely useless. But I'm an adult now, and he still does it to me and has been doing it my entire life. I want to stand up to him the next time he does it, but like I said earlier, he will do whatever it takes to protect his ego and he will go insane lengths to do it. I'm afraid that things will get physical as well if I do stand up to him, so I'm lost on what I should do.
