We all have bad days: they can ruin our mood for a couple of minutes, for hours, for the entire day, or even longer. Some bad days are worse than others. So, choose the worst day you've had recently (go back a couple of days if you have to. If you're one of those lucky people bad luck can't seem to find, then go back even further.) Try writing a poem or a short paragraph of that day. However, don't write a point by point of everything that happened as if it was a report. Instead write an exaggeration of everything bad that could have happened to you. For example, instead of loosing your keys you could have left your cell on the bus and realized it when you got off. You start chasing the bus, only to slip on a puddle in front of a large crowd. So, the poem or paragraph (more if you want) should be something like "this is what happened but my day could have been so much worse". It'll make you laugh and get over your bad day... hopefully. If not, try some chocolates.
