I have to get out into nature and find my center. I read something that a person such as myself that is diagnosed as an empath or highly intuitive person has to literally be around water to be soothed. Then I delved into aryvedic healing which is thousands of years old and it says the same thing that water soothes the soul of people with too much fire.
Try some very soothing music I love music by Aurah it helps me calm down. Unfortunately rock music makes me want to party and then I go into grief mode for my doc. IT's a trigger. But Bam I hope you can find how to tame the beast.
I sometimes think I have it figured out and then something comes out of blue moon that upsets me. Have you tried deep breathing exercises? You've been very supportive of me and I wish I could help you too. You are an inspiration for me on this board.
