Anna posts a snippet of her writing.

Twenty bucks says that the main character is a stand-in for Anna, and her "healing from trauma" is surrounding herself with human doormats. I hope Anna's husband is hiding money for the divorce.
Poly is basically the Geek Social Fallacies, plus sex. A perfect haven of consent and communication where everyone is a Friend Who Is Accepted As They Are and conflict just magically doesn't happen for some reason. Infinite friendship and sex on demand without any of the effort that goes into relationships. This is appealing to Anna, because she has a history of chimping out when someone tells her no.
Anything that would damage the Friendship needs to be suppressed. Feelings of jealousy, resentment, abandonment, etc. all need to be suppressed, or else you're just causing conflict and betraying the implied agreement in the group to all be chill. In the long run, this works out about as well as you'd expect. Of course, Anna thinks that this would never happen to her!
There's a saying I think is appropriate here: "No matter where you go, there you are." No matter how much we want to be different, there's just no getting away from ourselves. In the attempt to get away from being with ourselves, we search for something or someone to make us happy; the grass constantly appears greener someplace else. But in every relationship and every situation, there we are again.
Ultimately we can't keep running or hiding from our problems. If you're unhappy on the inside, declaring yourself to be poly, transgender, or anything else isn't going to magically make that unhappiness inside of you go away. You carry that burden with you, no matter where you go or what you call yourself. Sooner or later, you're going to have to deal with yourself. Anna yeeted her teets to try and escape from herself, and it didn't work at all. It became a narcotic she drugs herself with to hide from the pain that is now festering inside of her.
