According to surveys, more than a quarter of Brits feel that this is the day they feel most alone in the whole year.
But Kelly Langdon is determined to change that.

Pictured: Kelly is inviting people to have a chat over a hot beverage in order to boost their mood on ‘Blue Monday’.
The St. Helier resident has set up a gazebo in town, which islanders can visit for a hot beverage and a chat in a bid to raise a smile on a tough day.
“When talking face-to-face with someone who is happy, your brain fires up the neurons associated with the same feeling, promoting happiness in you… I hope that by doing this I am able to promote happiness and positivity among the community and make some people’s day just that little bit brighter,” she explained.
It’s not the first time the islander has attempted to boost the mood of the local community.
She was the mystery artist behind the positivity post-its that flooded town last September.

The initiative, which took around 18 hours from start to finish, saw the window of the former Next building covered in around 400 coloured squares each featuring a unique message she had handwritten.
She described the display, which was created with the help of her partner and best friend in the dead of night between 03:00 and 04:00, as “a way to brighten people’s days”.
Kelly told Express at the time: “So many people asked me, “Why?” and each time I responded with, “Why not?” In a world that’s focused on the negative, I wanted the positive to shine through. If there’s one message I want people to take from this it’s just “You’re doing great. Keep going. Just remember to breathe.”
Islanders can catch her for a mood-boosting chat today between 07:00 and 19:00.
Kelly isn’t the only one looking to lift spirits, however. A number of ‘paper people’ scattered around town are hoping to do the same.
Each is carrying a number of envelopes featuring positive messages available for islanders to take with them on their – hopefully – merry way.
