My ex female coworker beat me up, what should I do?

I’m lonely in this world. You might now believe it but I’m anonymous. I’m not trying to show off.
She was drunk and kept insulting me and her husband so I got tired and told her that she’s being flirting with all my partners including my husband and no one has ever noticed her and she started beating me up.
