When my kids argue with each other it’s a major trigger. I get severe anxiety. I can’t figure out why.
Are you close with your siblings if you have any? Could they relate to childhood memories? 
There is no harder job than raising a child…except raising more than 1
. I think every parent is pulling their hair out over this problem. It’s so frustrating! Unfortunately, all I can think of is powerlessness. Go out with your sober sisters and vent as much as you need to
Lop hopefully one day I'll be able to know what that's like!

I hope so too! I hope to be here to listen to you vent lol. Mine are 23 and 21 now. They figured out a few years ago that it’s better to join forces, and torture my wife and I 
Did you have a chaotic childhood with lots of yelling?
I am a “peace keeper,” have been since childhood, because if there was any calm in my life as a child, it was because of me keeping the peace between people or defusing situations between family members. I get that severe anxiety, to the point of dissociation, when tension is high, people are angry, mad, or simply unhappy. Anxiety happens because next comes fighting and arguing and that is when I literally curl up in the fetal position, doesn’t matter where I am, and emotionally turn off. Anger, which I feel fuels most arguments, is an emotion that scared the living daylights out of me. Other peoples anger, my anger, doesn’t matter. People who are a dry, including myself, are too unpredictable for me. I am legitimately fearful when anger is expressed.
I don’t have advice, but only share how I relate and my story, as it relates, to hopefully help you, feel less alone, and perhaps inspire a different way of thinking.
