When I am unorganised my anxiety is at it's worst, I find writing lists helps me reduce the fear I will forget them and the myraid of other fears and worries that could happen if I did forget them. It's a vicious circle. Knowing your own triggers is very important as it's the first step to reducing them. I haven't written my worries down but am a huge list person and have excel stats to boot. My panic attacks have subsided for now but next time I feel them rising I will have to remember this technique.
