One thing they really do not want, is to be diagnosed. You are correct, mood stabilizers, anti depressants, etc.. would probably be helpful. However, in her view, there is nothing wrong with her. Even when she may start to think there is something wrong she will dismiss it and convince herself otherwise. This continues until they get tired of running, hit rock bottom, or something, and hopefully awaken.
My W actually said she thought she was going crazy, but she realized that a crazy person would not think they were going crazy, so therefore she was not going crazy.
I also suggested she should see a doctor. Ha, that went over like a lead balloon.
She was one confused woman. I say was, because now she is deep in replay and she has no room for confusion. Her fantasy must be maintained at all costs. So things like self reflection, getting a check up, etc... are out the window.
The chances of conveying something to her are slim. Even if you do, it probably would only stick until she spins again. She needs to get to a place where she sees the benefit of seeing a MD for herself.
I love job’s saying. I heard it a few times.
Keep focus on yourself. Focus on her and you will go bonkers.
You’re doing good.

Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
