Growing up, I was "taught" / conditioned to "endure" severe, chronic stress.
This led to an accumulation of adverse events I was too stressed to effectively manage. Including especially physical injuries that had lasting negative effects.
I "hung in there" until my early 40's, when a career blow knocked the last pin out from under me.
I knew what I needed and wanted to do next. But I was frozen.
Physical health issues have continued to accumulate and to paint me into a corner.
Guard your physical health! Without it, life is much harder, and one problem tends to become two, become three...
Your physical health is the basis of your mental health and well-being. When you are physically unhealthy, it is much harder to be positive and productive. Especially when symptoms weigh on you persistently and take away your ability to focus and think effectively and to be comfortably social.
There is precious little in life that is worth the sacrifice of your physical health. And beware of scenarios that suggest or demand a trade-off against some future promise.
Those reassurances most often simply serve the person or system demanding the sacrifice. And it is a sacrifice -- don't expect to "get it back."
