TW for drug abuse, sibling quarrels, underage drug use/drinking, animal endangerment
||So basically my younger sister has been doing weed, nicotine, stuff like that, and she's 15. We're close. Or we were. She keeps getting caught for this stuff, and every single time, she says that she'll stop. But here's the thing, along with doing this stuff, she just makes generally bad decisions. But this time, she crossed a line.||
||She had her friends over, and it's a couple days after my birthday. Right? So her and her friends go outside, and I go outside to check on them since it's late. They then ask me to bring them food, shit like that. They finished my birthday cake. They left all the food outside. It was stuff my dog couldn't have. My dog keeps going outside, my older sister found out why, they left everything outside. I go into my bathroom, and they completely tore it up (my younger sister and I share a bathroom). Turns out, they were smoking marijuana. They got the munchies, and mostly finished my birthday cake, but they left it outside, and my DOG FINISHED IT and got sick. Vomiting all throughout the next day. And now every single word I hear from her mouth is a lie. I know it is. I am completely giving her the cold shoulder. She comes into my room, I tell her to get out. She asks me to watch a movie, I say no. She says she's trying to mend our relationship, but I am not on her side anymore. She keeps crossing the line, and coming back like she did absolutely nothing. Like I shouldn't be mad at her.||
||For context, this is about her sixth time being caught doing drugs/getting drunk since she was thirteen (five times within the past year though, and I have tried to support her and be on her side each time). Also, she is not allowed to go in her room because we don't know if she's smoking/vaping/drinking in there, and they may send her to either military school or catholic school.||
Is it valid for me to be mad and pissed off and ignoring her? Or AITA?
