Saturation

You wake up in the morning and get the news that something bad has happened to one of your friends or something bad has happened to you and when you feel nothing about it emotionally, You've reached the point of saturation.

What does it actually mean?

It means that shit can't hurt you anymore. It doesn't matter what it is and who it is, You just won't feel anything towards it or them. For example, Your S/O cuts ties off with you and you're sitting there listening to them giving their reasons for the breakup and you don't feel sad or angry or agitated. You basically feel nothing at the moment.

Why does this happen?

This happens mostly because of past experiences or trauma which makes a person numb and emotionless. Repeated bad experiences make the brain and the body acquainted with a certain type of sadness that never fades away and it results in a person gearing up for what's about to come even when they're in a good place.

Happiness is short-lived because you're always thinking about what might happen next and when the situation or the person proves it, You're barely hurt. Anticipating what can happen will always save you from getting a scar too deep but it can also make you emotionless, And there's no way you can hurt a person who is emotionless than by showing him/her how to love again and then taking it all away.

Being emotionless is a good thing but not always because there's a requirement as to when you need to use certain emotions and when the requirement is not fulfilled, People see you as being abnormal.

Never lose yourself to people/situations that are not worth it.
