I have a really short temper,... advice on how I can avoid such tipping points in future arguments or fights.
I've had a similar problem most of my life. It's not easy, but there are several strategies that have helped me.
First of all, such a reaction is purely physical, and frequently is the product of well-practiced habit. It involves the amygdala -- the part of the brain associated with fight or flight situations. It deals more with emotion than reason. And it is the part of the brain activated
before reason. To break a bad habit takes work and lots of practice. Start with self-awareness. Examine, as often as possible, your exact feelings. Take full responsibility for them, much as Christ took immense responsibility on the cross. Realize that physical reactions are non-spiritual in nature. We need to cultivate being spirit -- the true child of God mentioned in Genesis 1:26, implied in Genesis 6:3, and reinforced by John 3.
While you are practicing your new habit of patience and loving responsibility for everything the other person does to you (turning the other cheek), it might prove helpful to eliminate all activities that favor the amygdala hair-trigger reaction. Avoid for awhile all caffeine, alcohol, alarming news media, emotionally upsetting movies, heated arguments, etc. The Globalist-Leftists (Pro-Death Cult) like to push people's buttons with bad news, enlarging the amygdala and consequently shrinking the prefrontal cortex, thus reducing intelligence and increasing hair-trigger emotionalism.
Practice faith in God -- not merely "belief" -- but the perfection of humble confidence in God that allows you to act as spirit and not a Homo sapiens body. A rock cannot pray, and neither can a physical body or ego. It takes spirit to communicate with the Heavenly Father, so we need to wake up as spirit (be reborn of the spirit, as Christ said).
Practice True Forgiveness. This involves, not forgetting as in losing a memory, but forgetting as in an assault being reduced to extreme unimportance. Love the other person as yourself. Be generous in allowing them to have their viewpoint and their assault (verbal or physical). Be grateful for the opportunity. Be responsible for their assault against you. Be humble to their needs. And be confident that God will take care of you no matter what happens.
I hope this helps.
