FML - Need Advice

I didn’t know where else to share this so here i am back on ns. today at dinner with my extended family and my cousin was talking about this party she was going to (i was hearing about this party at the skatepark all day). i knew that some people i have beef with were there. my cousin is the most straight edge person i know but the friends she’s been hanging out with (the ones she was going to the party with) are terrible influences on her. while she was talking about it to me i got a terrible feeling in my gut. she’s the type to drink to make her friends think she’s cool and she was going to drive. so when she asked if i wanted to go i said yes because then i could drive and know she’ll make it home safe. so we picked up her friends they got drunk all was well. we are partying and that’s when i see the people i have beef with. i instantly start having a panic attack. i hate being around them because they just stare at me and talk shit. by now one of my cousins friends was extremely drunk and upset because she had recently gotten broken up with (she has a REALLY bad reputation around here). she sees the guy that just broke up with her and grabs my hand like we are dating. she tells me “act like we are dating i have to make that guy jealous”. i say no because i know all the old homies that hate me are staring at me. but she starts being super touchy and makes it look exactly like we are dating. i look over at the old homies and they are laughing up a storm. so i walk outside with two of my cousins friends to grab a cig from the car and the bouncers told us we couldn’t come back in if we leave. so they walk back inside and i was lagging behind a little. i was into the house and they are GONE. so i walk back outside and am currently standing outside of the house on ns so people think i’m texting someone. there’s an hour before i have to take them home and i’m almost done typing this so what the fuck do i do? please help this is the gnarliest situation ever.
