I messed up with my family, i don’t know what to do

i messed up really bad, i recently turned 16 and we just came back from my birthday trip, me and my moms birthday are 5 days apart (important). My parents said they were sending me to my grandmothers just after we got back.

Currently they have a flea infestation at their house and i didn’t wanna go bc im always getting bit no matter what. So i asked if we could leave sunday instead but i think i said something wrong bc my mom started flipping out and yelled at me to just stay and stay alone. So my mom left me and took my sister to my grandmas by herself. We argued during the trip but made up so i think she was still a little mad about that

She said she was going to a big city in my state to celebrate her birthday and me staying ruined it bc it selfish and never think about anyone but myself. I didn’t know that’s what they’re were doing bc my mom and dad already went somewhere for my moms birthday. And my dad said i was fucked up and selfish for saying that bc i’m only thinking that i don’t wanna go to my grandmas and nothing thinking that my mom want to celebrate her birthday freely

i kept trying to tell them i didn’t mean it like that bc i have trouble with not thinking before i speak

i’m sorry for the poor writing this just happened and frantic and crying bc i know i messed up and don’t know how to fix it or if its fixable
