Having one of those days or 2.........

It's a hard thing to do - ideally you want to think everything through so you can get some perspective and clarity, but at the same time not get anxious about cancer, treatment, disruption to your plans and life. It's virtually impossible. All you can do is bits at a time. When you feel anxious, do something as pleasant as possible or as mind occupying as possible. Writing things down I found really helpful, and deep breathing is really good. So is sitting and actively, consciously thinking about nothing. Good practice to stop your mind running away with you. When you feel better, make plans for tomorrow. Not next week, just tomorrow. One day at a time. Half the time we can get anxious about things that never happen. This is still your life, it's not really on hold, it's just taken a turn you hadn't planned. Some of it will not be great, but some if it may be more interesting or revealing than you might imagine. Best wishes.
