OKLAHOMA CITY -- Feeling depressed? You're not alone. Today is 'Blue Monday'- the most miserable day of the year for many.

The term Blue Monday was first used a few years ago by a psychologist who said the third Monday of January is the most depressing day of the year. But in 2014, 'Blue Monday' came early.

According to a mental health group, the perfect formula for depression is formed when winter weather is combined with debt, post-Christmas blues, the inability to keep New Year resolutions, low motivation and the need to take action.

"You got all these forces coming together so it's a little depressing," said Michael O'Rourke, wellness director at KimRay Inc.

O'Rourke was hired at the Oklahoma City-based oil and gas equipment manufacturer to motivate workers to live more healthy lifestyles. It's a growing trend among businesses.

O'Rourke said the programs are designed to boost employees' spirits.

"They're more energetic. They're happier. They're more outgoing," O'Rourke said.

Depression levels are expected to be lower this year because Blue Monday fell on a federal holiday, meaning more people had the day off work.

Hundreds of people flocked to Lake Hefner to enjoy the nice weather. Several said it wasn't a depressing day at all.

"I choose everyday to be happy," said Debra Litton, Ponca City resident. "It's a choice, and that's the choice I make."
