I was a heroin addict for five years and I got clean around this time two years ago. This is always a difficult time of year for me: my father died around this time when I was 12-years-old; I live in the northern latitudes so it's dark all the time; and since it's around the time I got clean I start getting bad cravings again.

I want to buy a smart trainer for my bike but they're all sold out at the moment. I'm too scared to ride on the roads at this time of year: it's permanent twilight, the roads are always wet which disguises potholes, and there are dead leaves everywhere.

I know that exercise really helps, so I hope I can get that smart trainer soon. I've been going for short walks but I really need that kind of exercise that leaves you struggling to think afterwards.
