What followed was a period, after about six months of this, of abject depression. I turned up at the station in the morning, went to work, went to the station to come home, and messed around on the internet all night. Going anywhere other than work was not possible, especially in the evenings when the last train is at 9.30pm or so. The railway line I live on just runs into the city where I work, nowhere else, it's a minor branch, so going anywhere else was a lengthy and expensive undertaking.
It was starting to make me ill - I never did anything, saw anyone, just work-home-work. I had to buy a car to enable me to carry on living here, otherwise I would have quit. Now, I have a fairly active life, I have the opportunity to do all kinds of things, and my quality of life is vastly improved.
Not having a car is OK if all you want to do is go to work!
