I am so done

Its my bday tmr and ive been so fucking nervous because my family can NEVER just get along or act normal. Every special occasion is ruined by us. We were gna leave today to go stay up at the mountain to snowboard for my bday, and i could inv some friends. Yesterday everybody was fighting, and treating me like shit. My brother every time he’d be around me, would call me stupid and rtrded. My mom calls me worse so this didnt effect me, and i ignored him. I literally just said nothing. Then he starts talking about my childhood dog who died a couple months ago, he said “you didnt appreciate her enough, she loved me more then u” … bro actually wtf is wrong w u ?? I started crying because that day i was missing her alot, and i do feel guilt for not spending more time w her. My mom heard him say this and didnt care. Then my brother started pestering her and she lost her shit on everyone and then her and my dad started fighting. Things like this r normal for me so i just went to my room and took a nap waiting for my friend to come stay the night(she was gna dog sit for us bc we were leaving for my bday) my mom kept coming in and calling me lazy and getting mad at me for having a nap- her reason being she worked 8 hours so i just shouldnt be tired. LIKE WTF OH MY FUCKING GOD DUDE WHAT? I just said fuck off and she did. Friend got to my place, and she has been around my family plenty, she knows how we treat eachother. I woke up at 6am, to my mom getting mad at me bc APPARENTLY I was supposed to pack up everyones snowboard gear and pack the truck. Nobody ever told me this, i was told to wax the boards, and i couldnt even do that because last night i kept asking my mom where the wax kit was, and she told me in the basement at the bottom of the stairs, so i check, its not there, and i go back up and ask her like ten more fucking times where it is and she kept getting mad at me and calling me stupid saying its at the bottom of the stairs. I then asked her to come get it with me and she told me to fuck off and went to her room. Like these people are so frustrating to live wirh they genuinely make me want to end it holy fuck.

Whatever, so i wake up in the morning and my brother is refusing to wake up bc he doesnt want to come, and then my mom gets mad at me bc i didnt pack last night. Even though it took me 10 minutes. I woke up at 6, we were supposed to all leave at 7. Im ready by 730 and by now my mom is in bed saying shes not going. Im assuming she was already drunk or something. I then start begging her to just leave the house and a bunch of shit happened and things led to another. She then starts smashing every one of my birthday gifts. I didnt care about the gifts just the principle of it. She called me names and ripped up frames photos of me and my childhood dog. My friends were there to pick me up and i just took my gear and settled w the fact that i would just snowboard w them for the day. They all know whats happening and this one friend who i didnt even want there was being such a fucking bitch to me and he was just fucking rude the whole time. We didnt end up going anyways because something was wrong w the drivers tire. Now im just chilling at a friends house . They told me if their mother did that to them they wouldnt talk to her ever again. But i feel guilt about the situation and i am somehow starting to believe it is my fault even though logically it isnt. I am tired of living with this fucking narcissist mom and mentally fucked up family like they all fucking suck
