I noticed that when I am tired from a difficult or long task (ex walking too far or working for a long time), I become very tired and it shows from my facial expression, speed, and attitude.

I feel sluggish and unable to have a good mood.

My mother is very upset when I behave this way, and she always tells me to control my emotions and even if I'm tired or hungry, still smile, laugh, and have lots of energy.

It's very difficult for me to smile and laugh when I'm so tired and hungry.

How can I control my emotions despite being tired or hungry?

Thank you
