I have catastrophic thinking all the time.
It just comes naturally unfortunately.
I apply CBT techniques and it sometimes helps but not all the time.
It’s very frustrating.
I think that this is exactly the right kind of thinking.
My expectations of life are very very low.
I expect the worst, never to be cured, never to be able to lead the life I want to lead.
I am ready to suffer my whole life.
When this is the starting point, you are never down,
and the only thing that might happen is pleasant surprises. @zeno is right.
Mmm I think that he is talking about the irrational side of the catastrophic thinking, the one dominated by fear and despair; and not ours of tranquility and mindfulness.
If you practice having thoughts and letting them go it can help you to sweep thoughts aside when you need to.
After that you need to replace the thoughts with something in the present, like focusing on your surroundings. I just take something nearby and examine it closely, appreciating every aspect of it and thinking about where it came from and how amazing it is.
