I struggle to explain how I can tell I have fatigue versus being tired.
It does physically feel like pressure. But I think that veers a bit close to what is said is experienced in high anxiety.
It’s not the same.
This is more like standing chest high in water and trying to breathe. It’s not pressure on the chest, but the feeling of being pushed in all directions, and no matter how deeply you breathe it feels like air is being pushed out. And sometimes that does actually happen.
Much like in water limbs feel strangely supported and heavy at the same time.
