We obsess over it not because it's going to happen imminently, we obsess over it because of our lovely blend of genetics and emotional traumas.
Sometimes to get over TMS we need to force our noses INTO that because our unconscious is doing it without our permission. A Producer who was describing me to a publisher once said "He has a Humorous approach to the Macabre"... I suppose I have been preoccupied with death since a young age and it leaks out in my writing.
I lost my Nanny and Father in a few months time at age 5. I was certain it was my fault. I deserved to die. I went to more funerals before I was 10 than I can count....and then when I was 14 another teenager just like me (preoccupied with death) was hit and killed by a drunk driver while we were riding through Nova Scotia. The last thing he said to me was a joke about Death and Funerals...
That triggered some of the worst OCD and obsession. Only severe substance abuse made it go away. I have had a lot of help in the intervening time...mostly of the tough love kind and it works better than anybody trying to assuage my fears.
"Yep...you are going to die and soon...So. How are you gonna LIVE?"
I wasn't afraid of dying. I was really afraid of living. When I focus on the present moment, it disintegrates all of that Obsession...
I was having some OCD like chest Pain a few months back...I thought "Oh crap...I am having a heart attack and gonna die"
Then I 'inspected myself'...what was I afraid of REALLY? The only thought I had was "Who is gonna take care of Sophie?" (My dog).
Later when talking to my son, I obliquely mentioned that fear to him, and he told me that if anything ever happened to me, He would take care of her, no problem.
I am officially 'free to go'.... Life is fun, but what if the next thing is even better? I would have wasted all of that life worrying about moving into a better zip code!!!!...THAT would suck.
It's good that you talk about it...let it out into the light and see it for what it is..
