Yes OP I have kids...surely you didn't think I meant that I really want us all to die?
This is the thing - for most people this sort of 'information' stops just outside our headspace and we can joke about it, it isn't frightening, it's just a silly idea that some people like to propagate.
For the rest of us, it doesn't stop, it goes right in and undermines our entirethinking.
I've been in both places and can understand how you feel. But you need to see that it isn't anything outside of you, making you anxious. It's purely how you are reacting to something that most people choose not to react to.
Maybe if you figure out what you're really afraid of you could work on some techniques to keep that under control and stop being so afraid - but putting it onto something as bizarre as this is just a displacement activity and won't help you cope.
If you've had CBT you'll know what I'm on about - good luck and did I mention, stop having any caffeine at all - tea, coffee, cola, chocolate. see how that works for a week or so - you might be surprised (if you do have caffeine now that is - if you don't then ignore me)
