May I suggest something for you to do when you start to perseverate over an issue you believe will go badly??
I've learned to do this as I have a tendancy to over worry about things. But I am also a planner too, so this is what I do.
1. Write down the issue in Big Letter at the top of the paper.
2. Draw a line down the middle of the paper
3. List on one side of the paper, the worst that could happen in that situation
4. List on the other side of the paper, the best and/or most logical things that can happen.
5. Review the worst side. What can you "plan" to do to recover from the worst possible happening? Write it down.
6. Review the best side of the paper. Tell yourself over and over again that 95% of the time, the worst does NOT happen in most situations.
The thing with this is that you have to be completely honest and logical about the bad/good possible outcomes. It helps us to learn how to prepare for things that bother us and give us anxiety. When we have a plan in place, we are more likely to be more comfortable and not shocked when the worst does happen (which is rare)
I hope you try it out and practice it. I think you will find that you will train yourself to think more logically and feel less emotionally about issues in your life. Good luck with it ((((((((((((((((((((dec)))))))))))))))))))))
