If it can't be solved, worrying will do no good.” The challenge for you, if you are worried about something, is not to dwell on the problem, but to translate it into research questions in order to determine whether it is solvable. Which information is functional in your situation? Who could you talk to in order to test your assumptions? Who can help you to break down your problem into manageable portions and provide you with advice?
‘Parking your brains.’ If you sprain or bruise your arm, you bandage it. If you keep fretting and worrying about a problem, you could say that your prefrontal cortex is bruised. It needs a bandage. You can do this by ‘parking your brains’. Buy a notebook or pad. Every time you think about your problem, whatever your thoughts, you write this down. Then you close the notebook and say the following to these thoughts: “I can see you and I can hear you and I will get back to you on [choose a day in the near or far future] at [choose a time].” And make sure you do!

Give the problem you wrote down the time and the kind of attention that feels right to you.
