I dont have the best relationship with my father and he makes my mom the middle-man of us.

For some context, I am 16 years old living with my mom and dad. I dont know if I cant be on here at 16, but thats besides the point. I just need help. I love my dad, and I love my mom. So much. I will admit i have not been the best kid recently because im female teenager and I've been emotional. But thats normal for all teens to be a little ignorant and rude sometimes(I hope).

My father has never been an issue, he is kind, loving, and caring. But the past 1-2 year(s), he has started drinking hard alcohol and beer, everyday. He usually gets home from work around 3pm and starts to drink beer, and occasionally the hard stuff. Talking to him when he drinks is impossible. Nothing I say is right, nothing i do is right, and im always wrong. He is always right. Sometimes if I've done all of my chores and there's nothing for him to yell at me about, he will bring up the past of how i didnt throw something away or I didnt do something properly. I dont know why he does that. My mom has recently had hip surgery and he calls her out for not doing stuff around the house to help him, even when she is still recovering. When he drinks, I dont know who he is. Now it just sounds like we need to go to therapy, and I agree. The problem is that he doesnt want to own up to his addiction and has to shift the blame onto anything but him.

Now onto the second reason I need help- I over hear my dad saying the he thinks I hate him and ignore him to my mom. What is true is that I avoid him when he is drunk. Because I dont want to argue. My mom tells me everything he says about me. He asks her to tell me to do my chores more or that I didnt do them on time. Instead of telling me. Recently, my mom told me that he said hes going to start "ignoring" me. This morning (hes sober) I heard him asking her "why does she hate me, why does she despise me". Sometimes i find my mom crying, and i think that he emotionally abuses her. I love my dad, but I miss my dad. I miss my dad before he started drinking. Even when hes sober, he feels like an angry being. It was never like that a few years back, and I just wish that he would stop drinking. What do I do?
