Why what did I do

I was just lying in bed in my own room bc I have no energy to get up and Im really sadand my mom came in and started yelling at me and I begged her to leave and she didn't want to until I started to cry and then she yelled even more bc I'm embarrassing her bc the guests in another room would hear me silently crying and apologizing to her as if they wouldn't hear her yelling I hate when my parents do this just enter my rum make fun of me bully the hell out of me complain then pity themselves then say "God please save me" and look at me like I'm th worst garbage ever why won't they just leave the room when I ask them why do they have to do that as I was writing thisshe came back angry and yelled at me even more and didn't wanna leave no matter how much I begged her. I just want her to have the tiniest bit of understanding and tolerate me she doesn't even have to love me. This isn't the first time this happened btw
