Ok so what do you think?

You shouldn't miss out on something you like because of a fear. The thoughts that were going through your head seem on topic and you were only thinking about numbers which suggests that your mind wasn't wondering. If this is a long term problem you should consider medication because it doesn't seem fair to miss something you enjoy. If you don't want those feelings then you should stay home to watch the dog whisperer cause it's a good show. whatever you decide, you should enjoy
