I literally dragged myself out for a 20 minute slow run. I was nervous about people looking at me so I started run down a quiet road. By the time I'd reached a busier road I was concentrating on my breathing and my knackered legs so much I forgot about anyone seeing me. When I'm anxious I can feel the adrenaline rushing through me so I think running will help to use some of that excess adrenaline up. Hopefully!
