She has literally no excuse. She knows it's wrong, just today she retold her epic trash drama. For better or worse, Teru's community is permanently poisoned by the people here. She can't do anything to change it, and it's not her fault, so she shouldn't feel as bad as she does about it, but that doesn't excuse playing into them. Even if literally every IRL friend ditched her, she still has her manager, her boss, and the rest of the AG talents to talk to. She says that they're all asleep when she's up, but she's a literal NEET, she can be awake whenever.
This is the problem: Teru herself, and her fans, are too weak-willed to correct course and stop this shenanigan's. So the same thing that's happened before is going to happen: Teru gets a talking to, becomes "reformed," does decent streams until she starts breaking down and then the cycle repeats. If she's incapable of doing this, then she needs to stop. Take a break, go on hiatus, whatever. Sort out her problems, and come back to streaming with a healthy mindset. She can't be doing this shit over and over.
