Idk how to feel abt my parents

My mom says she gives me privacy and wouldn't go through my stuff but i came home from my friends house and she litterally went theough my whole room while i was gone. She knows i didnt want her to go through my stuff and clean it out but she still did. And when i said i was pissed abt it, my parents js laughed at me. My dad even said "oh my god hes fine, hes always happy" even though my parents know im definitely not happy. They found out i sh but didn't even care. My dads and alcoholic but hes pretty cool when hes not drinking, but when he is drinking im scared of him tbh. He screams at me and my brother and he trashed my room before. My mom screams at me a lot and expects too much from me. But theyre still my parents so i feel obligated to like them. Someone give me some advice bc idk how to feel bc my mom always talks abt how i have good parants but idrk 🤷‍♂️
