This technique is similar to an earlier exercise. The first thing to remember with problem solving is that you need to recognise the signs that there is or could be a problem. Learn to be aware of the triggers. As soon as you start to notice the pressure building up, and you feel a creeping feeling of stress, make a list.
Write down everything that is bothering you - the big problems, but also the little things that have been nagging at the back of your mind. However small or trivial it may seem, if it has been whizzing round your brain lately, write it down. Once you have everything on paper you will be able to think more clearly, and it won't look or feel as bad once you have got it out of your head.
Stress is a medical condition and it can have a serious effect on your health. If you think you are suffering from stress it is crucial that you consult a medical professional.
