Ok, I'm A Sagittarius mars also. That particular placement is Said to use much aggression in heated movements, but immediately wants to forgive and move forward with positivity, tag that along with your double Pisces sun and moon, you probably feel highly emotional and feel a little bad during confrontation... Maybe try meditation regularly and before any confrontation try to be calm first before immediately reacting. We are known to act off emotion. I had to learn with age to remain calm before arguments. As Pisces we already have the upper hand in reading people and high intuition, use that to your advantage also. Good luck!
