@surreality This thread has been pretty uncomfortable to read. I'm sorry you're going through this but I really don't think this forum can help you figure it out. You've made a lot of vague posts about this in the past, I think, that it seems unlikely things are going to change. If it is affecting your real life, you need to go to real people, whether that means the relevant law enforcement, a therapist or counselor.
The only element you control here is yourself. Get away from the people causing you stress. If that means leaving a game you like because you can't avoid them, that's a small price to pay in the long run for your mental health. The same goes for mutual friends or chat groups. And frankly, I would strongly consider what you get out of this forum VS what affect this forum has on your wellbeing. Your interactions and relationships with the people causing you stress are unlikely to change and they are unlikely to remove themselves from here. Again, you can only control yourself.
