Jon developed Moodscope after suffering from mood swings
Beating the blues could be as simple as getting over a bad day or as complicated as dealing with depression.
Jon Cousins, from Peterborough, has not only won his own battle with depression but has developed his own sadness fighting technique, called Moodscope.
He said: "I invented this system that lets me accurately measure my mood and asked friends to receive my scores by email.
"When they started getting my scores my depression started to get sorted out."
Talking to the BBC Cambridgeshire Peterborough Breakfast Show, Jon said he had to find a way of dealing with his mental health issues by himself.
He explained: "About three years ago I was diagnosed with a form of bipolar affective disorder.
"That means you have alternating periods of feeling incredible highs and incredible lows.
"The highs I could deal with but the lows I couldn't deal with."
That led to the concept of Moodscope, where Jon would test himself every morning to measure his mood and then send the results to friends, who would in turn help to cheer him up.
The scheme is currently being trialled for free online and users can try the test, which essentially asks you to answer questions about how you feel with an answer on a scale of zero to three.
Jon said: "It's like a little online card game. Because the interaction is online it's very unobtrusive.
"It's a way of measuring your mood accurately every day and then sharing it with someone who's agreed to buddy you.
"The NHS are now starting to have a look at it and the Institute of Psychiatry are researching the idea."
Jon has taken the concept one step further after finding he was able to deal with his depression better when surrounded by people with a similar illness.
He said: "The idea with Weight Watchers is if you want to slim down a bit one of the best ways is to join a group of people who can supply social support.
"I figured that something similar might work for mental wellbeing."
The result is Glumbusters - classes in Peterborough designed to help all kinds of people boost their moods.
If everything goes to plan Jon's personal treatment for depression could become a national phenomenon.
