It’s always five days before my period

I have become more cognizant of when I fall into my pre menstrual anguish. I start feeling very mean, ocd mental patterns become more intense, negative, and impulsive. I am sharply aware of it now, but the more sharply aware of it I become, the more it bothers me psychically. Like wow I am a literal homosapien primate. I’m feeling very regretful and ooga booga right now.
