Dealing with a difficult person?

It seems like you've been going through a lot of emotional stress and I could relate in some ways (my parents are amazing but ive seen fathers that could be real jerks towards their children) First of all, could it be that your dad is going through something difficult in his own life and the way he deals with it is by haring you? Maybe your dad is having a hard time with the fact that his kids are growing up and they don't need him as much, he could be trying to get attention from his kids. Maybe your dad is fighting some other battle in his life and he doesn't want to talk about it so instead he behaves that way. You should express your feelings and try talking to your dad, try to spend some quality time with him or do nice things for him like make him a sandwich or go through family albums with him or even talk about things HE enjoys. Your dad could be going through something, fathers sometimes dont like to show their families theyre in pain cause theyre the "man" of the house. I hope everything works out for you and your family!
