Why are they like this?

Does anyone else’s parents like drag the fuck outta you and humiliate you one day, then kind ignore you/ice you out after the verbal beating/argument and don’t apologize and just say “we do this because we love you and we don’t the best for you” like no you make it your life’s mission to control me and ostracize me because I’m gay and not Christian (agnostic btw). Like sometimes I’m grateful that I’m just as stubborn as them because if I wasn’t i don’t even want to know what I would be or be doing. I have a hard time being vulnerable in front of my parents, especially my mom and I made the mistake of doing so about a month ago when I had a huge mental breakdown, like I was hysterical crying on the floor and she mocked the way I cried a few days ago because she was angry with me over my grades/lack of studying. She barely said anything to me yesterday either and opens my bedroom door, I’m laying in bed. She goes “are you sleeping or studying?”, I was only relaxing a lot since I didn’t have any school today. But yeah I’m 17 and a junior in highschool and I wonder if I’ll make it, I struggle with depression and other mental health issues but they believe it’s my own fault because I’m not Christian
