What is something that your parents did while you were growing up that absolutely boiled your piss?

I honestly don’t know if I’m crazy or not for thinking my parents have borderline abused me my whole life. Sometimes I blame myself other times I blame them; Yikes I’m about to unload some wild shit and try and keep it short because I sympathise with all of you. Hope I am not identified as I’m 20 and still living with them till I can afford to move out. Biological Dad died when I was 2 (cancer) - he and biological Mum were huge drug addicts. She very badly neglected me (left me on my own to so drugs etc) and so I was taken off her. My dad’s sister married her then partner and applied to court(? not sure how the process works exactly) to adopt me. All my life growing up my “dad” would absolutely fly off the handle at me for anything at all, even crying - and I mean inches away from my face, his spit burning my eyes, screaming at me. Obviously did not stop me crying. My “mum” never defended me. I would be dragged around by her while shopping, bumping into people she hadn’t seen in years, with her telling them how amazing her and my dad were for taking me in and how hard it had been… for them. At age 11 my biological mum came back on the scene and took them to court for visitation rights. I only found out about this a month before the final court date as they chose to keep it from me. I had to attend that court date, which my biological mum won. Skipping a bunch of trauma from that, all my life’s shit has culminated in me being a very, very anxious, sometimes very very depressed person. I’m also autistic which means I can’t really hear my own tone of voice. If I sound off with my dad, I get screamed at for “speaking like that” to him, so bad that people who come to my house (friends, partners etc) tell me how out of order it is. Last year it all came to a head when he would not stop getting at me and I told him to fuck off while it was just me, him and my current girlfriend at home. Admittedly I shouldn’t have told him to fuck off, but he immediately flew into a rage. Knowing I’d fucked up I simply tried to walk away, crying and apologising, but instead his arm flew in front of my face (almost hitting me), slamming the kitchen door shut in front of me blocking my exit. This set off a major panic attack and I got absolute tunnel vision, stumbling backwards out of the kitchen onto the patio where he proceeded to try and physically drag me back in the house across the floor (in just my underwear so i ended up covered in dirt and scratches) all while I begged him to just go away. He then followed me and my girlfriend upstairs begging her to take his side that he hadn’t literally just assaulted me. About a year before this, I told him to leave me the fuck alone and I closed the bathroom door behind me, only for him to yank it open with his fist held up in front of my face. This is just my dad. My mum is something else entirely, tbh. But yeah. There’s so much more I’m just way too tired rn.
