Does anyone know something that could get me through seeing my family for the weekend?

Hey so this is gonna be quick one unlike my usual posts. Context for the uninitiated, i have anger issues and they flare up mostly with my family, because of unprocessed trauma (i'm working on it)

My first instinct was smoking, it makes me incredibly docile and sleepy, so i think i could manage with that. And my parents aren't really bothered by my smoking, as long as i do it outside, they've accepted a long ago that i'm not really gonna go anywhere in life. So it's gonna be the least risky and also the most enjoyable route to managing this. My grandma would lose her mind tho, i can't tell her.

I'm not a danger to myself or others, but my sister was reposting some shit about "oh my brother has anger issues lmao" and it was funny, i can say that it is something i struggle with, but it did get under my skin a bit. So i need to lock in so she can't hold it over my head. Otherwise i would just go there like usual and just try to not get agitated or something, i don't really have coping skills.

That's all, no need for concern btw we win these
