Bad day- what is the real definition of that???

Everyone had one, everyone went through one but how do you define a bad day. Where the good day ends and the bad day starts??? Can a bad day be a good one in a long run? Today is may 28 and I’m having really bad day, every minute something else goes wrong. Just took a min to write this post. Trying to take a mental break to look at the big picture. Maybe that would help me to stop the avalanche of bad things keep happening to me…..
