ughhhh no words can express how I feel

I'm a totally hypocrite I know, but my 23 year old brother flirts with girl younger than me(I'm 17). He started talking to a girl in my grade (she a hoe like fr,) and so they were a thing and they hooked up than she randomly fucking showed up at our house with another man! Who happens to be pals with my brother. And I feel like I have no right to be upset becuase I hooked up with a 24 year old and. But he is going behind my parents back, (as I did I know😫). And doing this and now he's going out with "friends" tonight but I know she's going and he told me I can't go sledding with our normal group of friends(that we go sledding with all the time) becuase it's only going to be guys, but she's going to be there and we hate each other we always have! And I don't know why but when ever I hear her name it makes me want to punch something. And he always says how she's nothing and this and that! I'm just god I want to scream! And so I texted some of off friends and they said they had no idea about sledding tonight and didn't plan to go! Soooo Idk why but I'm pissed! And I just needed to vent! And yes I know I'm a just as bad but I only hung out with the 24 year old twice and than we cut it off he's always trying to get with guys my age and sometimes even younger! And that's embarrassing to me when I have to go to school and some sophomore tells me my brother was hitting on them last night! I don't know what to do.
