I have trouble understanding why so often passive-aggressive types are the ones who end up with the most people in their corners, defending them--citing all their "personal problems"--while these defenders seem quite unaware of the lives the troublemakers leave in turmoil as they go around whispering & telling tales without ever being held responsible for the consequences of their acts.

Maybe this woman's victims need to meet with the GM as a non-aggressive but quietly self-affirming group before she can harm any others.

In the meantime I feel for you. Losing your temper after holding it for so long... This feels like a failure, I'm sure, but you are paying such a price for it. You feel so badly & would take it back. Isn't forgiveness possible? It seems like time now to forgive yourself & move on. You do, after all, have the work consequences to deal with.

Hug time?
