I have had issues with depression all my life, and it's probably true to say there was a tendency towards it even when I was very young, during my schooldays. There was often - and this is quite common with comics - a sense of not feeling as if I belonged anywhere.
I'm just saying that at least for the foreseeable future there won't be any more touring.
Never under any circumstances take a sleeping pill and a laxative on the same night.
