Just some ideas that may help you?
I 've learned when I get PTSD rage is to walk away from the situation.
Get away, or I will snap and say something I will regret.
Where ever you are, just walk into any other room, place, garden, just move away.
It saves tearing up relationships with people.
When your calmer, maybe next day then deal with the situation.
Having to drive in heavy traffic is always stressful can you listen to a CD, music, etc?
Check out Tony Robbins he is a motivational speaker and talks about how to change the state you are in by what
you are thinking.
Highly recommend.
Listening to him has really helped me in a positive way.
I hope it will help you.
Warmest regards and best wishes.
