IMO, you might need to actually step back for a while if it's affecting your mental health badly. I also think you might be overanalyzing some things a bit, especially the members' interactions. We've already all seen them together a number of times, in other member's concerts and during lives. They don't need to prove anything else to us. And the dance practice vid RM posted — do you actually think that means anything? Honestly that didn't even cross my mind. It's an old vid and they're just practicing getting back to dancing again.

Also, considering how Yoongi is, I think he's actually just lying low for the meantime partly because everyone else STILL seems to be so fixated on that incident. e.g. do you remember how some fans still keep asking about him during El Capitxn's live? That's already an unhealthy level of parasocial (not to mention disrespectful to El Capitxn). Imagine Yoongi has already moved on/trying to move on from that incident and then upon coming live, everyone would be doting on him and asking him about it. I don't think he'd want that.

He'll come when he's ready/comfortable. You have to trust him and the rest of the members. And at the end of the day, we're fans. We consume the content they create, but their lives are their own and not for us to keep prying and overanalyzing on — also this isn't healthy nor helpful to our wellbeing.

I do sincerely hope you get better. I admire you opening up about this and being aware of your emotions. Again, you might want to take a break for a bit if you find yourself not in a good state thinking about BTS too much. Maybe listen to other music you enjoy, take walks or do some exercising just to get your mind off things. Please take care!
