'I'm feeling exhausted'. That's said by millions of people of all ages, backgrounds and beliefs. I want to ask what that actually means and to do that, I'm going to use myself as the example, since it's the best evidence I have. Is 'exhaustion' a subjective term, or does it have a more scientific, objective meaning?

For me, exhaustion is a condition that goes beyond the mere physical. While my physical exhaustion may stem from working too hard or lack of sleep, my emotional exhaustion (i) has come from prolonged stress, leading to feelings of irritability, overwhelm or apathy, leaving me feeling drained and detached. My mental exhaustion, with cognitive overload and diminished focus, makes my decision-making harder, slower and less reliable.

That's where I'm at as I write this.

I find talking to others helps, including my family, but I don't want to burden people with my worries. I hate waking up with the prospect of facing a new day, not sure what will face me and how I'll meet any challenges. I feel inadequate, helpless to change events. I've been in this place before and come out of the other end seeing the sunlight, but this feels different. My exhaustion is on a different level.

There are other terms that need to be placed in the mix when discussing exhaustion - fatigue (ii) and psychological stress (iii) amongst others. I don't want to go down those areas here (please view the links below).

I know I'm not alone with this, but I feel like I am. One day I'll feel better about the situation. I hope that day comes soon.

You don't have to face your exhaustion alone. I'm not. There's no shame to admit you have reached your limits, rather it's a strength. People do care, so let them care for you in your time of challenge.
