It seems like you are still very very focused on why she is saying, doing and thinking. I think there are three things you can do right away that can help you. At least it will reduce your pain.
First, zero talk of OM. If she is ready to disrespect you with OM, she needs to do it alone.
Second, pull back and detach from her. You have got to me more focused on how you feel than how she feels. What she feels is not your problem. She fired you from that job.
Third, Are there any goals you can write down that are just for you, so make yourself a better person? Action goals, something we can measure?
