What a frustrating day!

I had a frustrating day when I woke up. I was having a runny nose but it was getting better at the end of the day, including my mood too. I always wonder why people gets frustrated? Is it hormones that easily changes the person's mood or the mind? Or am I too serious over the matter? Sometimes, it might be a small matter but it causes me to get frustrated easily. Luckily, I get over it after some time.


My way of clearing frustration? Perhaps keep myself occupied.
