One day you'll laugh about it

I awoke this morning with a low mood and low energy. Morning only lasted a few hours before I needed a nap.
When I woke up from that I was running late to meet someone for lunch. I rushed into the city and felt the rush absorb me. Unfortunately my friend was also running late so I was forced to linger on the street, the crush of people swarming, going about their own business as I tried to reestablish my place amongst them. It has been a few weeks since I've been around crowds and I felt anxious. I very nearly got on a tram and went home.
My friend turned up and we sat outside the State Library and chatted. I recounted my story and when I came to the part about hiding out in a hollow tree, he laughed.
People have been saying to me that one day I'll be able to look back at this episode or incident and laugh. But nobody else has actually laughed yet. Everyone is very respectful and concerned, some seem almost fearful, but my friend was the first to actually laugh about it.
It felt good.
I'm still exhausted but my mood definitely picked up. 
Tomorrow is the first day back at work. Hopefully I can remember the lesson of today and make it through even if my mood is low and perhaps find just one thing to turn it around.
