Forced to go on a church retreat I didn’t want, now I’m the "sinner" for being annoyed?

So, earlier today my parents hit a new level of logic that I’m still trying to process.

They basically forced me to go to this church youth retreat. I told them straight up I didn't want to go and that the "advice" they give there isn't even beneficial to me. Specifically: Most of the relationship advice they peddle is low-key toxic and basically conditions people to stay in situations that don't favor them. They’ve literally told me I’m not allowed to date anyway, so why am I sitting through hours of lectures on "godly relationships"? When I brought this up, it turned into a massive argument. Their response? They told me my anger is a "sin." Apparently, I’m supposed to just be thrilled to go because "everyone else is going" and "why would you want to stay home?" (Uh, because my bed and my peace of mind are at home?)

Anyway, I ended up going because they’d already paid for me without even asking. I spent 95% of the time there on my phone with my AirPods in, just trying to zone out and survive the boredom. I didn't enjoy a single second of it.

I just got back, and now they’re actually mad at me because I’m not smiling and acting all "spiritually refreshed." Like... I told you I didn't want to go! Why are you surprised I’m not having a blast?

I’m just exhausted. I can't wait until I'm financially independent so I don't have to play these games anymore.
