I can’t do this anymore

I’m 13, homeschooled have literally no friends for this reason. My parents have put this second mother role on me and I can’t take it anymore, im always taking care of my siblings never getting free time for myself and not having any friends because of this. I just had a fight with them for simply asking my younger bitchy brother to pick up a controller since I nearly stepped on it and asked in my nicest tone possible, my dad yells at me saying I could’ve just picked it up but me myself and I doesn’t want to buy a new controller with my money for him to break again. I then say ______ gets everything he wants and you guys yell at me for literally nothing and I can’t do anything right, they say hell no he doesn’t and at this time their eating while I’m having a full blown panic attack, I have all this anxiety and problems from past people and my parents in general that I can never let out because low and behold I’m a people pleaser. The only person I feel safe talking to is my older brother, please just tell me how I tell them all this, I’m sick and tired depressed with anxiety and so much more I probably don’t know about. How do I tell them I wanna go back to school? How do I tell them I hate being their second mother? How do I tell them all this stuff I’ve been hiding locked away in my mind and heart without them yelling at me and saying I’m an attention seeker?
