Hey Eve!

Like you said, it sounds like she should not be the admin of a mental health forum!
I know you didn't ask for it, but I hope you don't mind my advice. I'd leave the forum. It sounds toxic and unhealthy to you, your mental health (its stressing you out), and could get in the way of your recovery. I hope you don't take this as a judgment though. I would think you'd have reasons for staying, too.

That aside though, I empathize with the way you're feeling. I'd feel powerless and at the same time, I'd want to take her down. Lol. Which would really, in turn, lead to more powerlessness feelings for me.

Sorry you're experiencing anxiety over this.
