I'm sorry Blackgnat.
COM is right on, we do cycle through the stages of grief.
Look to your arsenal of ways to feel better, one immediate thing you can do is go take a walk. Studies show that within 11 minutes, our brains shift our mood. Call a friend to have lunch with.....go have your nails done.
The pathways in the brain get worn into a ditch called FEAR and when we respond the way you are, the transmitters of the brain continue down that same path, over and over and over again.........we have the power to change that pathway by our thoughts and actions........meditation, yoga, walking, exercise, shifting our thinking onto something else, even if we have to continue trying to shift it over and over works. It's a practice, but it works.
One thing that I used to do a lot is go for a drive. I live about an hour from the ocean so it's a nice drive and there is something about standing on the shore of the vast ocean that changes ones perspective. The woods can do that too, nature..........it's very healing.
This stuff hurts, there's no doubt about it. But we can minimize and shorten the impact on us by the ways we respond. Go grab your day and try to enjoy it. Sending hugs your way.............
