How do I overcome the fear of Friday 13th?
As with any fear, understanding it is the first step to dealing with it. Your fear is so widespread it even has a scientific name (paraskevidekatriaphobia). There are lots of ideas as to where it started, for example some people think it started with the Christian story of Christ and the 12 Apostles, making 13 an unlucky number, but in fact supersition about the number 13 is older than that.
So is there any reason to fear Friday the 13th? No, is the short answer. What happens is that if you are nervous on this day, you are more likely to make mistakes and so perhaps have an accident, but people who aren't worried about this day have no problems at all. In other words, whether you have problems on Friday the 13 is entirely up to you! if you just go ahead and get on with your normal life, everything will be fine.
