no you are not alone. I only have a bit over half of Richard’s 71 years experience, but I can tell you from my personal experience that when I try to guess the future, or try to change the past, my energy is used and I get tired. When I get tired, bad things happen.
There are many ways to stay in the present, I try to appreciate things in new ways, try as best as I can to practice gratitude, worked many years on self-esteem, and remind myself every day that while planning is OK, trying to determine or control the future is trouble for me. One day at a time!
I went through about 5 years of actual panic attacks. Therapy, exercise such as yoga and walking, self-talk (and esteem) and for me a bit of spiritual guidance and a bit less of caffeine, helped me through a very rough time.
Anyway, if you haven’t, please also check in with your endo because there are also diabetes issues that affect adrenalin and it’s best to eliminate those first. good luck!
