Emptiness. Suppressed. Locked. That's how I would describe the emotional state of people in emotional apathy. It's like this state where you avoid facing your emotions, and the results are starting to show.
The flow in which you express emotions as a person is blocked. Apathy cuts it off, so you as a person feels something is off. You are not yourself, and it's painful.
More painful because maybe you don't see or enjoy things the same way anymore. Perhaps there are moments when you just can't control your emotions anymore and everything is in disarray.
I like to speak to that. Hopefully, I can help you understand this state better, so you can work towards breaking out of it.
