This feels important to read, and I appreciate the author's candor.

You have to remember that not every character (for lack of a better word) in every story you read, needs to be morally justified in their thoughts, emotions, and actions. This author is angry, humiliated, scared for their life. It's not compelling to discuss their thoughts without empathy. If you don't think you would feel or say the same, were you in their shoes, imagine "what would need to be true for me to feel, think, act that way?"

This way of empathizing, where you assume the role of another without assuming superiority, may help you better understand what the author is trying to communicate. What must it be like, what might they be going through, how vulnerable must it feel?

The author is dealing with a minute-by-minute reminder of how easy their life could end. Most readers will have never experienced this. On top of this, they are dependent on a company and system, which is only tangentially designed to keep their body alive. During a time when the author dare to have a vacation away from home, an experience something many of us don't realize we take for granted (maybe not financially, but the fact we are able-bodied enough), they are faced with losing their life like never before.

I think the author needs no justification for their apparent rage. It's refreshing to hear a voice we don't often hear. We are often raised being told these feelings of grief and rage are bad, unmoral, crass. That we should judge others who express them.

Here is one person's story you happened to come across. If you have trouble empathizing, remember, at best, we are all just temporarily able-bodied. You may do well to reckon with these experiences now, before your existential challenges are picked apart as inconvenient or uncomfortable for others.
