So, it’s mid-January and we have well and truly left the fun and frolics of the festive period behind. The decorations are back in the loft and all we have left are failed resolutions, grey skies, big bills and even bigger bulges! Which is why today is apparently one of the most depressing days of the year.

Do you agree? Or are you a young introvert who is happy all the time? Let us know your thoughts.
