I know how you feel. My father used to be abusive and curse at me, my siblings and my mother.
I know it's not easy to get over it, but he's ur father. If he has a heart deep inside him, he will change for the better. I mean ever since my mom got sick my dad completely changed, well, he's still a little health forum now and then ever since I got preggo but yeah.
I stuck with my father through everything. For everything he called me and my mother. He used to say I was bad luck to his life and even called me a dog! But I stuck with it. My mom even left him, brought my brother and sister to cali and stayed there for seven months. She tried to take me but they fought and my dad made me stay with him. I tried committing suicide and I used to always burn my arms. I still have the scars and everytime I look at them it just reminds me of when that time period when my father treated me like an animal.
He blamed me for phone bills, water bills, electric, everything! Even gas! So I ran away.. And I regret those times.
I know its hard when your father health forum and blames you for everything, even though you didnt do anything, but he's ur father. Just be patient.
Don't do anything stupid, like I said, wait till your a little older and if you can't take it anymore, move out.
Im sure he has a good heart deep inside. I didnt know my father did. I never knew he loved me. But when I got pregnant, he got so depressed. He even said "she doesn't know how much I love her". I was hurt, too. But I didn't say anything, he treated me my mother and siblings like caca!
Once he see's how great you and your family are, he will realize all the bad caca he did. If he see's..He will change for the better. Just dont think your alone on this.
