What helps you when you are down or stressed

I was advised to do this when I was first diagnosed 12 years ago and it helped then as it does now. Buy or find a small box. Each day at about the same time write down your negative feelings and fears on strips of paper. Read them, fold them up , put them in the box and put it away. I had about 30 mins a day when I allowed myself to feel down but by writing the feelings down it seemed to compartmentalise them. After a while I found myself writing positive things and the negatives diminished. Perhaps it is the teacher in me but writing really helped then and helps now. Writing and exercise rule!
