Nothing but an expectation you have created with another that you're struggling to keep.
So don't lie or embellish your promises to others with unnecessary commitments and promises.
If your ability to meet agreements starts to drop short, share that with the other party honestly.
So... is stress so mystical as gets portrayed. I think not.
It will come from another... but more importantly... it will come from another based on your relationship with that other.
Even a virus... it will overwhelm if your position as the alpha organism drops... the virus will prepare to take over.
Your position as the alpha organism only begins to drop with stress that you yourself have brought on because of your associations.
How's that for total control?
Victum? I think not.
Your action? I think so.
Tuff to face? Definitely yes.
Best of luck,
