Where does mars occur in your chart and how is it aspected? Do you have conflicts/stressors in that area of your life? I have mars in the 3rd house (siblings) and I argue/fight with my siblings regularly. I also have it poorly aspected in opposition with saturn in the 9th (philosophy/religion). Most of our arguments are over philosophies and spiritual practices (I left my religion when I was younger which caused a lot of mayhem to this day) Edit: wording
